Dear Harald.

As for me, I hvae found the source of the problem: I had identical help
files in different directories; when duplicate files are removed, it works.

Hope it will help you.

Eric.

PS: to the Scilab team: I think it would be wothwhile to have in that case
an explicit message, such as: "error: duplicate help files in your
distribution".

Dear Eric,

you mean that files with exactly the same *contents* written in the same 
language are in different directories? Or do you think the problem is that files 
with the same *name* are in different directories? 


The online help of my toolbox is written in German, English and Japanese. The 
files for German version reside in de_DE, the English files in en_US and the 
files in Japanese are located in ja_JP. There are three files called 
AnalyzeBlobs.xml for example. There is one German, one English and one Japanese 
version. The names are identical and so are the XML tags, but the contents are 
different, of course.Should I rename the files, e.g. AnalyzeBlobs.xml in 
AnalyzeBlobs_de.xml, AnalyzeBlobs_en.xml and AnalyzeBlobs_ja.xml?

Harald

Dear Harald,

In my case, the files had exactly the same name and content (I maintain help
in English only). Suppressing the doubles allowed to remove the error.

If this is not the case for you. To check if the problems comes from the
names (not the content) you can either try :
- to keep help in only one language.
- to rename the help files with suffixes (_en, _de, _jp for instances).

Hope it helps.

Eric.

Subject: Using ATOMS Modules
Message-ID: <AANLkTi=Wj=xKUD8gU48K+n3ySTvfx5XSjemXM65Nhgec@mail.gmail.com>

Hi all,
I'm trying to use ATOMS modules.

I followed the wiki http://wiki.scilab.org/ATOMS In the case, the number
theory module, named 'number'. I'm not quite sure how to use it.

What I did was:

atomsInstall('dispmat');
atomsInstall('apifun');
atomsInstall('number', '1.1');

In here: http://atoms.scilab.org/toolboxes/number/1.1 are listed some
functions, like 'number_carmichael'. I tried the following:

number_carmichael();

But it didn't work.

Am I doing it right?

Thanks,

Subject: Number format changes in editvar function
Message-ID: <BBAE4BCB36F2443982FD4DF69303D9B5@PC5>

Hi all:

When I edit a matrix of doubles using "editvar" function, it changes the normal format I am using in the console. Example: 1234.5 in the console, changes to 1.234,5 in the editvar worksheet.

Is there a way to avoid this change ?  The OS is Windows XP Pro, Scilab version is 5.3.0

I will appreciate any information about this.

Best regards,
J.L.V.

Hi,

As far as I know, the lpsolve interface is not available for Scilab 5.3. 
It is not available in ATOMS. A linear solver which is available in 
Scilab 5.3 is linpro, from the quapro module :

http://atoms.scilab.org/toolboxes/quapro

Is there a reason why you specifically need the lpsolve module ?

Best regards,

Micha?l Baudin

Hi,

I think you may have to check whether you are connecting to the internet
directly or through a proxy server. If you are connecting through a proxy,
please follow these steps (See the help file for atomsSetConfig):


-->atomsSetConfig('useProxy','True')

-->atomsSetConfig('proxyHost',<whatever the proxy server is, as a string,
i.e., within quotes>)

// e.g., atomsSetConfig('proxyHost',"198.201.2.2")

-->atomsSetConfig('proxyPort',<port number as a string, i.e., within
quotes>)

// e.g., atomsSetConfig('proxyPort',"3120")

-->atomsSetConfig('proxyUser',<whatever your username is, as a string, i.e.,
within quotes>)

// e.g., atomsSetConfig('proxyUser',' guilherme')

-->atomsSetConfig('proxyPassword',<whatever your password is, as a string,
i.e., within quotes>)

// e.g., atomsSetConfig('proxyPassword','guilherme123')


You can find more on help regarding 'atomsSetConfig'

Regards,

Sam

Hi,

Did you restart Scilab before actually running the functions ?

If yes, this is a bug. If not, this is your fault, but you should be 
able to dynamically load the module with atomsLoad("number"), for example.

Hi,

In order to solve a nonlinear equation in Scilab, you can use the fsolve 
function:

help fsolve

This requires that you define the nonlinear function f(x) associated 
with the f(x)=0 equation.

Best regards,

Micha?l Baudin

Hi Micha?l,

Thanks for the answer.

Indeed, that was my fault. I didn't read the wiki carefully :(

Subject: Wrong HDF5 library version
Message-ID: <ifvclt$sjh$1@dough.gmane.org>

Hi,

I just installed scilab-5.3.0-beta-4 on OpenSUSE 11.3 from 
OpenSUSE-Education repository. The installation also pulled libhdf5-0 
1.8.5 and jhdf5 2.6.1 among other packages.

When I run Scilab and want to start Xcos, I get the following error message:

      xcos: Unable to load the hdf5-java (jhdf5) library.
      Expecting version [1, 8, 4] ; Getting version [1, 8, 5] .
      while executing a callback

Unfortunately, only libhdf5 1.8.5 is provided as a package by OpenSUSE. 
How can I resolve this dependency problem?

Thanks,

JC Francois

Is it possible to add a grid to a plot such that there are grid lines drawn for the subticks as well as for the main ticks?
If so, how do I do it?

Ok, it is working!
I used the tag property.
I discovered that SCILAB (findobj function) looks for in the code 
everywhere and that whatever the location of the tag (function in a 
function).
The notion of the local or global variable do not exist for the research 
of the tag with the findobject function.

Thank you for your help.

Best regards.

As far as I know there is no minor grid in scilab. However the help page 
of the "grid" function (Scilab manual >> Matlab to Scilab Conversion 
Tips > Matlab-Scilab equivalents > G > grid (Matlab function)) provides 
some tips to emulate this.

If anyone has the same problem :

the mingw atoms module is not compatible with *any* mingw compiler, but 
only with the package provided by equation.com

Thanks, I will do that. I just thought there was a way to configure 
Scilab to accept a newer revision of the lib.

Responding to myself... actually there is a way:

set the following environment variable to ignore version check:
HDF5_DISABLE_VERSION_CHECK=1

Hi Adrien,

Scilab loads Mingw correctly. 

My Windows 7 home edition is 64 bits, but I installed Scilab 5.3 for 32 bits 
Windows,
and runs very well.

Adrien, follow this procedure:

1) Download: 
ftp://ftp.equation.com/gcc/gcc-4.5.1-32.exe 
2) Execute that file;

3) Go to the URL: http://atoms.scilab.org/toolboxes/mingw/

and download the file: mingw_0.6-2.bin.windows.zip

4) Unzip it and transfer the folder mingw_0.6 to C:\Program Files 
(x86)\scilab-5.3.0\modules

5) Then, initialize Scilab and type the command: atomsInstall(['mingw','0.6']) 

6)?Type in Scilab: quit

7) Afterthat, initialize Scilab again and it will load the Mingw toolbox !!

Well, I followed that procedure exactly?and Scilab works well ... No error 
message appeared !

All best,
Reinaldo.

If anyone has the same problem : 

the mingw atoms module is not compatible with *any* mingw compiler, but only 
with the package provided by equation.com

Subject: How to load 16bit TIFF image in Scilab?
Message-ID: <4D248F45.6010201@laas.fr>

Hi everyone,

I try to load 16bit grayscale TIFF image into Scilab.
I tried to use SIVP as it handles TIFF images.
However, it does not import 16bit TIFF correctly.
It seems to me that it interprets the 16bit image as an 8 bit one, which 
results in a great loss of information.
Does anyone have some experience with handling 16bits images in Scilab?
Alternatively, do you know some tool I could use to convert my 16bit 
image in a csv or any other format that Scilab can import?

Thank you in advance,

Antoine

Have a look at ImageMagick or possibly libTIFF

In the Linux world, GIMP or ImagJ may accomplish what you are wanting to accomplish.

I already played with ImageMagick but I don't know how to use it to 
convert in a format scilab can import.
As for libTIFF, I am currently playing with it in an attempt to write my 
own import function for scilab.

Gimp (at least the version I have on Fedora13) does not support 16bit.

Another possibility- goetiff
I am not sure about the Fedora repositories, but Ubuntu packages has a "Science" section that lists a lot of specialized processing packages from a variety of sources that may offer the conversion feature you are looking for.

A bit more information about ImagJ, from the documentation:

"16-bit and 32-bit grayscale images are not directly displayable on 
computer monitors, which typically can show only 256 shades of gray. 
Therefore, the data are mapped to 8-bits by windowing. The window 
defines the range of gray values that are displayed: values below the 
window are made black, while values above the window are white. The 
window is defined by minimum and maximum values that can be modified 
using Image>Adjust>Brightness/Contrast."

Is this the sort of function you are looking for?

Not really, but thanks for the information.
In fact, we use a 16bit camera to acquire some signal that we process 
with Scilab. We don't really need to directly look at the unprocessed image.
We don't want to throw away information while processing the data.
Moreover, we need to be able to compare the relative intensity between 
to different images which mean we cannot adjust image settings 
independently.

Hello,
I am a beginner with scilab and I downloaded the free borland c compiler 
yesterday. I don't know what I have to do when
xcos or scicos say "Compiler not found " when I try to simulate
an electrical pattern ?

Hi,

 

Borland C compiler is not supported.

 

You can use Ms Visual studio Pro or Express ( <http://msdn.microsoft.com/en-us/express/aa718373> http://msdn.microsoft.com/en-us/express/aa718373)

Or mingw with   <http://atoms.scilab.org/toolboxes/mingw/0.6> http://atoms.scilab.org/toolboxes/mingw/0.6

Or lcc-win32 with  <http://atoms.scilab.org/toolboxes/lcc_windows> http://atoms.scilab.org/toolboxes/lcc_windows

 

Best regards

Hello,

I am a beginner with scilab and I downloaded the free borland c compiler 
yesterday. I don't know what I have to do when
 xcos or scicos say "Compiler not found " when I try to simulate
 an electrical pattern ?

Regards.

Subject: Linking to C from Scilab: looking for some advice
Message-ID: <4D25B45A.2000904@laas.fr>

Hi everyone,

As some of you have seen here, I was looking for a way to load 16bit 
tiff images in Scilab.
I found a way: compile a C routine that uses libtiff and link to it 
using "ilib_for_link".
It's the first time I manage to link to C code and I am looking for some 
advice on what is good/bad practice.
Is there a tutorial or an article on that?
I also have a specific question concerning "dynamic allocation".
More precisely, I would like in the end to get something like:

    image=openTIFF("test.tiff");

where "test.tiff" is an image of unknown width and height, and "image" a 
matrix of the same size than the image.
My problem is that it involves filling the "image" matrix without a 
priori knowing how big the matrix is.
Is there a way to do it properly using a single C call?
Or should I resort to something like

    function image=openTIFF("test.tiff")
        w=call("width_of_tiff","out",[1,1],1,"i");
        h=call("height_of_tiff","out",[1,1],1,"i");
        image=call("read_tiff","out",[h,w],1,"i");
    endfunction

that uses several calls to C?

Thanks in advance,

Antoine

Hello,

I cannot save any scinotes file. Whenever I attempt to save and conduct
another activity (i.e. save and execute, save and quit...) the program
merely returns to its original state before I selected that command.  If I
directly try to save I get "The file could not be saved" error. I am running
windows 7.

Thank you!

Hello,

Happy new year to you!

I think that the statement :

nm  =  nmplot_configure(nm,"-numberofvariables",1);


should be replaced with:


nm  =  neldermead_configure(nm,"-numberofvariables",9);

First, the nmplot component is only useful in 2D (i.e. with 2 variables).
Second, there are 9 parameters in your optimization problem, isn'it ?

Best regards,

Micha?l Baudin

Sujet: Stage d?veloppement interface DAKOTA / Scilab

Le logiciel DAKOTA (http://dakota.sandia.gov/) est un outil permettant d'effectuer des optimisations de tous types sur des pi?ces industrielles. Cet outil permet d'appeler des codes de calculs ainsi que des ex?cutables permettant de lancer des calculs. Il peut aussi appeler des scripts Matlab via une interface d?di?e.
Le but de ce stage sera de reprendre l'interface permettant de lancer des scripts Matlab et de la transformer afin de pouvoir lancer des scripts Scilab (http://www.scilab.org). Il faudra aussi d?velopper quelques exemples d'utilisation de cette interface.

Comp?tences :

Des connaissances en C / C++ sont indispensables.
Une connaissance de Matlab et / ou Scilab pourra ?tre utile.
La ma?trise du gestionnaire de version serait un plus.
Savoir communiquer, savoir r?diger. 

Les d?veloppements s'effectueront dans un environnement Linux.

Informations compl?mentaires : 

Le stage se d?roulera chez Hutchinson SA - Levallois-Perret - 92.
La r?mun?ration sera de:
?	784 ? net pour un stagiaire de fin d'?cole d'ing?nieur
?	655 ? net pour tout autre candidat

Subject: News on the wiki
Message-ID: <4D270AA6.1060107@scilab.org>

Hi,

There was recently several users asking for support of finite element 
tools in Scilab. As this question was asked regularly, we gathered the 
informations we have on the wiki :

http://wiki.scilab.org/Finite_Elements_in_Scilab

The goal of this page is to present the finite element tools which are 
available in the Scilab environment. It presents the Femtruss module and 
the connection between Scilab and the FreeFem, OpenFem and GetFem modules.

-- 

We often provide support for users who provide packages on Atoms. There 
are simple practices which are sometimes forgotten. The main reason is 
that we often tend to develop a program only for ourselves, and forget 
that other users may have troubles with the tools we have created. The 
most common of these advices are gathered on the wiki page :

http://wiki.scilab.org/Guidelines_To_Design_a_Module

In this page, we briefly present the "Toolbox skeleton". We also 
presents methods which avoid function name conflicts, advices on the 
help pages, the content of these pages and the API of a module.

-- 

There are several interesting resources on the web which compare the 
features and performances of Scilab versus other softwares, including 
Matlab, Octave, etc... We gathered these documents on the wiki, in the 
"Comparison of Scientific Technical Softwares" section of the Tutorials 
page:

http://wiki.scilab.org/Tutorials

They cover the years from 1999 to 2010. Most of them are very 
interesting. Still, we should be aware that some of the informations are 
not up-to-date, given that Scilab is constantly evolving.

Best regards,

Micha?l Baudin

Subject: dynamical simulations with scilab
Message-ID: <D0FE4A0F7910F4499DBC0FB25772F46452F57B@TAIPEI.intra.cea.fr>

hi everybody, I would like to do dynamical simulations with scilab on
hydraulic/thermal systems (many components hydraulically linked
together: valves, pumps, water tanks, heat pump, boiler... ) controlling
flowrates and temperature mainly . There are commercial simulation
environments for this but they introduce too many constraints in later
exploitation and distribution that's why I investigate the scilab way! I
have many existing models (blocks) in C and fortran that I would bring
to scilab (or link) environment : is there example of such use of scilab
(other than scilab simulations demos which are not oriented), is there a
place where I could ask and talk about this more specifcally ? thanks
for your advice.

Hi everybody,

 

I would like to make an independant executable of the program I maded

this ?

Where can I find detailed informations about distribution rules of such
an application?

 

Thanks,

Hi

you may find some answers reading the example in ilib_for_link documentation
type in scialb :

help ilib_for_link

be careful, you will need a C compiler installed in your coumputer. In 
linux, gcc will work with no problem, if you are using windows, i 
suggest you read carrefully this page, and more specifically the 
"description" section :

http://atoms.scilab.org/toolboxes/mingw/

mingw is not the only  supported C compiler, you can learn more by tiping :

help supported

which will get you to the list of supported compilers

Subject: statconn Server Basic Test and SCILAB
Message-ID: <AANLkTinx0qEZCfmN1e0Je1H8po2BZEzNaP+R=LjPsvbp@mail.gmail.com>

Hi,

I am *unable to successfully run the statconn Basic Server Test for SCILAB*.


My ultimate goal is to be able to have Excel speak with SCILAB functions
using a  toolbox like Scilab_XLL.

Here is what I did so far:

   - Installed SCILAB (scilab-5.3.0)
   - Installed statconn version 3.1.2.7.
   - Copied sciproxy from statconn directory to SCILAB's bin directory
   - Successfully ran Basic Server Test with R.


*The output from StatConnector Test*
Loading StatConnector Server... Done
Initializing SciLab...Function call failed
  Code: -2147221485
  Text: installation problem: unable to load connector
Releasing StatConnector Server...Done

And then a pop-up box with message: Method '~' of object '~' failed.

The log of DebugView is attached.

Thanks
Ashu

Why do you not use Scilab XLL in this case?

Subject: C->Scilab: Now I'm lost and need some directions
Message-ID: <4D2C7B82.8030400@laas.fr>

Hi all,

I am fighting to call some C code from within Scilab, or more precisely 
to add a primitive to Scilab using some C code I wrote.
I have a working C code and I managed to link it to Scilab by using 
"ilib_for_link".
It works, no problem.
Now I would like to bullet-proof it, that is to get it to work like a 
real scilab primitive.
For example, at the moment, if I try to open a file that do not exist 
(from within my C code), I just kill my Scilab session.
This is due to the way the error is treated in my C code.
I would prefer to get a normal Scilab error: "!--error 241, File does 
not exist".
In the end, I would like to handle all the usual scilab error (wrong 
number of arguments, wrong type, ...) gracefully.
What should I do?
I found bits and pieces here and there about how to link, what the 
interface should be like, how to use call, ... but I can't put the 
pieces together to get a big picture of what I should do.
I found "intersci" but it is obsolete. I found some articles but they 
are outdated ( http://www.saphir-control.fr/articles/lm15/article.html ).
Does anyone know a proper tutorial or *complete* example ( c_source, 
interface_source, build and example of use) on the subject?

Thank you in advance,

Antoine

Well, I didn't mention it, but I downloaded this module and I opened all 
the files I found and I was lost.
Basically I don't know where to start and which file does what and what 
I should modify to adapt to my c code.

I am experiencing the same thing: being lost in the toolbox skeleton.

I also find that typing "help api_scilab" does not help me at all right 
now. And i just understood today (thanks to allan's mail) that toolboxes 
is the modern way of doing what i do with call.

For now i am still using ilib_for_link and call, because of the very 
effective help of ilib_for_link, which does provide a complete example.

If anyone happens to have some guidelines, it would be very helpfull to 
make a wiki i think.

About that : i find extremely confusing the fact that there is, in 
scilab 5.3, documentation for both old and new scilab APIs, which i can 
still not distinghuish clearly. From my point of view, they are both 
called by a concatenation of "scilab" and "api", and i have the 
impression (which i also believe to be false, but anyway), that some 
pages from the new api are linked to old ones.

E.g : when i type "help api_scilab" i get in a doc page which includes 
"Straight and named access (See the call_scilab API) to variables.". 
Then i go to call_scilab_API, where an example uses stack-c.h and claims 
this is the old way.

At this point, i decided to wait scilab 6.0, hopping it will come with 
documentation about new api and no documentation about old API, to be 
sure to understand what to do and do it.

i am not willing to complain (i really love scilab) i am just trying to 
provide feedback

best regards, avs (and sorry about the spam, maybe this should be a 
whish in bugzilla)

Good to know I am not the only one.
I really started to feel dumb... I have been wandering with Scilab since 
2.something and for the first time I am really lost.

That's exactly what I was thinking about.
Is there anyone from the consortium who can provide us with some 
guidelines on the what-to-do and what-not-to-do when trying to build a 
primitive?

Hello Antoine,

Maybe could you have a look at forge.scilab.org where you could find
several projects.

I also had the feeling of turning in circles: I started from one bit of 
the new api (CheckLHS) and trying to find an example, after a few clics, 
I ended up on something that belong to the old api (call)...

Well, I cannot wait that long as I have some data waiting to be 
processed and I need to call some hand made C routine for that job...

Yes, I hope all this does not sound too negative, this is not the 
purpose of the discussion.
I am also really happy with Scilab and I always found the user list 
reactive and useful.
But for the first time, I did not have any answer that really helped me 
going forward.
Crossing fingers...

Thanks for the hint, I had a look at it but was a bit set back by the 
complexity of most projects.
I'll have another look to see whether I can find a small project where I 
can understand what to do.
Do you think it'll be easier to grasp than the toolbox_skeleton?
Because without tutorial- or beginner-oriented comments, I could not 
understand where to start and what to do to adapt it to my problem...

Maybe this one: http://forge.scilab.org/index.php/p/scimysql/
and more precisely:
http://forge.scilab.org/index.php/p/scimysql/source/tree/master/sci_gateway

I didn't try to compile it but in reading the code available in this
directory, I found it interesting...

Thanks, I'll check this tomorrow at work.
I was also thinking about:
http://forge.scilab.org/index.php/p/csv-readwrite/
as its purpose is close to the one of my C routine (read 16 bit tiff file).
I can't browse the sources now, so I don't know whether the comments are 
adapted to my level (newbeeee) in this field...

Reinstalling sivp as no effect on the problem and I can't reproduce the

Hi,

On Windows, i advice that you try Scilab 5.3.0 and SIVP for scilab 5.3.0
We fixed a memory leak which generated this error on Windows.

References: <igkgtn$2lf$1@dough.gmane.org>
Message-ID: <201101122200.26163.Andreas.Stewering-Bone@gmx.de>

Hello,

I have some questions about the Xcos or Scicos Event handling.


Normal blocks implement a

init
calc
end

Functions

I would like to implement fieldbus handling block

So it would be ideal to have a

init -> get configure information from every block
postinit-> prepare complex data structures (based on the configuration), malloc 
some memory
calc -> do IO
end -> release memory

functions.

There a many different flags for numerical events during calculation. Are there 
any plans or possibilities for adding new scicos flags during initialisation?


Another question:

If I have different XCos IO blocks which use the same infrastructur (like one 
block creating a tcp server port, sereral blocks which present data on this 
port). Is there a possibillity to share informations betwwen blocks during

configuration time (interface function)

or 

initialisation time (calculation function) without using global strucures

for example to get the amount of server blocks or data ports ?



Greatings 


Andreas

Hi,

You might be interested by the Stixbox module :

http://atoms.scilab.org/toolboxes/stixbox

There are various functions related to bootstrap :

  * ciboot : Various bootstrap confidence intervals
  * covboot : Bootstrap estimate of the variance of a parameter estimate
  * stdboot : Bootstrap estimate of the parameter standard deviation
  * rboot : Simulate a bootstrap resample from a sample

Does this fit your needs ?

Best regards,

Micha?l Baudin

Subject: I have some questions about int4sci  and ALIAS
Message-ID: <tencent_1ACEA2DD432B06C05CE768CB@qq.com>

I am a Chinese postgraduate student and interested to int4sci. I have some questions about int4sci 2.0. From the report ? int4sci : scilab interface for interval analysis, I know Int4Sci 2.0 will be released.When will it be released? Now, the system environment of ALIAS is linux. Can I use ALIAS by calling int4sci interface with ALIAS in Windows system after int4sci2.0 is released ?  By then, can source code of ALIAS be modified and compiled in windows ? .If I want to modify and compile ALIAS in windows for my experiment tool, can you give  some advices? It will be greatly appreciated if you can give me some suggestions and  answer my question.
Yours sincerely
Lili Tan

Hello,

You can found more informations on simulation flags on the
scicos_block4.h file.

The following flags are used on during the simulation:

DerivativeState
OutputUpdate            *
StateUpdate
OutputEventTiming
Initialization          *
Ending                  *
ReInitialization        *
	
You may implement the selected (with *) flags and use the work field to
store any information (an allocated data structure for example).

Hello David,

I know this flags,

it is more complex.

It would be very nice to have a postinit Flag to work on  configuration data 
(init the fieldbus based on the data),   which is fetched during init, before 
going into cyclic mode for IO-calculation. 

My target is realtime code generation, so doing initialisation stuff during 
cyclic mode is not very nice.

If you have a complex distributed IO Structure, the possible flags init, inout 
and end do not fit the needs.

Greatings

Andreas

Objet : [scilab-Users] I have some questions about int4sci and ALIAS

 

I am a Chinese postgraduate student and interested to int4sci. I have some questions about int4sci 2.0. From the report ? int4sci : scilab interface for interval analysis, I know Int4Sci 2.0 will be released.When will it be released? Now, the system environment of ALIAS is linux. Can I use ALIAS by calling int4sci interface with ALIAS in Windows system after int4sci2.0 is released ?  By then, can source code of ALIAS be modified and compiled in windows ? .If I want to modify and compile ALIAS in windows for my experiment tool, can you give  some advices? It will be greatly appreciated if you can give me some suggestions and  answer my question.

Yours sincerely

Lili Tan

Message-ID: <DF76479F9BB74A0FAC69960B0E21A0E7@miserylap>

Hello there,

 

Here You have a quite general Newton-Raphson function.

Just fill function F(x) and use the code below. :]

good luck and best regards.

 

function y=F(x)

  y=your formula;

endfunction

 

function x1=NewtonRaphson(f,x0,Epsf,Epsx,h)

  x1=x0;

  if h==[] then, h=1e-10; end; //step for numerical derivative computation

  while abs(f(x1))>Epsf | abs(x1-x0)>Epsx do //checking the condition to
finish iterations

    x0=x1;                                   

    df=(f(x0+h)-f(x0-h))/(2.0*h); //numerical derivative (central scheme)

    x1=x0-f(x0)/df; 

  end  

endfunction

 

 

 

x0 = starting value,

Epsf=0.0000000001;  

Epsx=0.00000001;

h=0.0000000001;

solution=NewtonRaphson(F,x0,Epsf,Epsx,h);

Subject: A kind question - xcos
Message-ID: <alpine.LRH.2.00.1101132352450.23263@omega.cie.put.poznan.pl>


A kind question,

I am trying to make a function for my students enabling them to give control 
system parameters via GUI, and then by pressing SIMULATION button to launch a 
simulation of a control system from xcos, but in such a way that no model 
window is shown, just the plot of, say, a step response (in the model).

THis is like something that can be done with SIM function of Matlab:
- in a function I assign variables to the Simulink space of variables,
- I launch the simulation with SIM
- all the data is stored in ToWorkspace block
- the figure is plotted without simulink model being shown.

Is there any such function in Scilab? I have run some research on this topic, 
but no function works as expected, besides the function that OPENS the xcos 
model.

Thank you very much for any clue or response,

There are some known issues with this.  It comes down to video drivers.  I
had the same problem and fixed it by downgrading my Nvidia driver two
versions.  I've seen reports where users with Intel cards are upgrading
drivers to resolve the issue.  This was with version of 5.2.2 but I doubt
much has changed as it was an issue with the video driver.

For information, we hope we will be able to tackle all these driver
issues in Scilab 5.4.
(we agree they are pretty boring)

Thanks

I succeeded in building a string, however I still have a problem :

I have read a character array in a file using 

fd=mopen(nom,"rb");
tab=mget(fd,"c",number_of_characters);
mclose(fd);

in tab I get the ascii code of each character (eg : 99 for 'c')

I would like to search a substring  in tab
substring="string to search"

if I use tab_string=strcat(code2str(tab)) or tab_string=string(code2str(tab)) and then start=strindex(tab,substring); it does not work since code2str does not give the inverse of the ascii code

for example : 
ascii('c')=99
code2str(99)= !

What is the difference between the ascii code and the "scilab" code ?

Hi,

Why not use the fsolve primitive of Scilab, which implements a more smarter
method (Powell method) than regular Newton's, and which does approximate
the derivative more precisely ?

function y=F(x)

   y=your formula;

endfunction

x=fsolve(x0,F);

Hi,

I've found out that the function "ascii" converts in both "direction", that solves my problem
ascii('c')=99
ascii(99)='c'

Hello,
This is a question related to the LAPACK or ATLAS libraries,
that are used by Scilab but external to it, for these operators
and other linear algebra ones.
You might search and ask to the dedicated websites.

Hi,

In most cases, the backslash operator uses a Gaussian elimination with 
row pivoting. In some cases, it uses a least squares algorithm.

See in "Programming in Scilab" :

http://forge.scilab.org/index.php/p/docprogscilab/downloads/

section 5.6, "References and notes".

"In the section 5.1.3, we presented a Gaussian elimination algorithm and 
stated
134 that this algorithm (but not the particular implementation that we 
presented) is
used in Scilab, behind the backslash operator. The actual behavior of 
the backslash
operator in Scilab is the following. First, we perform a call to the 
DGETRF LAPACK
routine, which decomposes the matrix A into PA = LU, where P is a 
permutation
matrix, L is a lower triangular matrix and U is an upper triangular 
matrix. The
diagonal entries of L are unity. Then we call the DGECON LAPACK routine, 
which
approximates the inverse of the 1-norm condition number of the matrix A. 
At this
point, there are two cases. If the condition number of the matrix is not 
too large,
then the system of linear equations is not ill-conditioned (this is not 
exact, because
the condition is only approximated, but the algorithms makes the 
hypothesis that
the estimation can be trusted). In this case, we call the DGETRS LAPACK 
routine,
which solves the linear system of equations by using the PA = LU 
decomposition.
More precisely, this step uses row permutations, and then the forward 
and backward
substitutions in order to compute the solution x depending on the 
right-hand side b.
In the other case, that is, if the matrix is ill-conditioned, we use a 
modi
fied version
of the DGELSY LAPACK routine, which solves the associated least-squares 
problem.
This choice may reduce the accuracy for matrices of intermediate 
condition [9]."

The inv function just solves the equation Ax=b with b=eye(A), so that it 
is just a particular call to essentially algorithms. Actually, the 
algorithm that you can find in :

http://gitweb.scilab.org/?p=scilab.git;a=blob;f=scilab/modules/linear_algebra/src/fortran/intdgetri.f;h=061fe92c5fbae006485493df93c77b8c26a59843;hb=HEAD

uses another routine, DGETRI:

http://www.netlib.org/lapack/double/dgetri.f

Best regards,

Micha?l

Hi,

That is true. But why not using the fsolve function ?

After all, the whole purpose of Scilab is to save time by providing 
these "basic" algorithms, isn'it ?

Hello,

I am using the "eqfir" and "remezb" functions to design FIR filters. The documentation on these functions in the Scilab help manual is very brief. Are there other sources of documentation where I can learn more about these functions? For example I would like to know what is the difference between these 3 functions - they each appear to do about the same thing. I would also like to know more about the algorithms  they each use and how to map the coefficients they produce to the various FIR circuit structures such as the direct form FIR structure and then be able to compute how many adders and how many registers are required.

Thank you,

I used the command 'global' but I surprised by its use.
Indeed, I have to define my variable as 'global' in the main program AND 
in the function where it has to be computed.
Is it normal?
 From my point of view, I thought that to define the global variable in 
the main program was sufficient!

Nota: The function is a callback function from a pushbutton.

In Scilab, all variables of the calling workspace are accessible
but read-only. If such a variable is modified e.g. inside a function,
this is in fact a local copy which is modified, not the variable of
the calling workspace. This explains the way that global variable
work in Scilab. If your variable is declared global in the calling
workspace, but not inside the function, when you modify the variable
in the function, you modify a local variable.

Hi users,

I see that Stixbox?module has a lot of statistical functions. 

I would like to know if those statistica functions were implemented in Scilab 
5.3 or
I need to download the Stixbox file and install it.

Thank you.

All best,
Reinaldo.

Subject: How to use multiple instances of a class in Modelica generic blocks ?
Message-ID: <OF4416AD4C.4395617D-ONC125781B.0037C0BE-C125781B.0038ADDD@notes.edfgdf.fr>



I got the message "too many files, please put all programs in a single file" in Xcos. I don't how to do so.
I would like to do so but it appears to me that Xcos/modelica makes a mistake by not considering a difference in a "class"
and a "class instance".
A class is the declaration.
A class instance is a usage, an item of that class.

In a modelica generic block, if I put a file name for example "test1.mo".
File "test1.mo" contains a class let say called "test1" so it is a declaration.

If I want to instanciate the class "test1" in multiple modelica blocks, Xcos will send me a  error message saying that I
declared multiple classes "test1".

My multiple modelica blocks (of the same class) should be only Instances not Classes.

How do you solve this inconsistency ?

Dear W. Grabellus,

there is no such thing as a German or English version of Scilab. If you want to 
use Scilab in English during a session, type 


        setlanguage('en_US')

If you want to use Scilab in English permanently, type

       setdefaultlanguage('en_US')

I hope this helps.

Best regards
Harald Galda

64 bit.
 
I always land up with a German version.

Hi,

Ok, now I remember, it is there :

http://forge.scilab.org/index.php/p/number/source/tree/HEAD/macros/number_ismember.sci

Unfortunately, I have not released this function in the binary release yet.
Here is a simplified version:

function tf = number_ismember ( a , s )
     // Array elements that are members of set.
     //
     // Calling Sequence
     // tf = number_ismember ( a , s )
     //
     // Parameters
     // a : a ma-by-na matrix
     // s : a 1-by-ns matrix
     // tf : a ma-by-na matrix of booleans, tf(i,j) is %t if there is an 
entry in s matching a(i,j).
     //
     // Description
     // Search in a the entries which are in s.
     //
     // Uses vectorized statements, based on the Kronecker product.
     // The intermediate memory required is ma*na*ns.
     //
     // Examples
     // a = (1:5)'
     // s = [0 2 4 6 8 10 12 14 16 18 20]
     // tf = number_ismember ( a , s )
     // expected = [%f %t %f %t %f]'
     //
     // // An example with a matrix
     // a = [
     // 7 35 14 86 76
     // 15 51 24 96 49
     // 35 40 46 35 93
     // 85 34 74 82 22
     // ];
     // s = [51 74 22 15 86]
     // tf = number_ismember(a, s)
     //
     // Authors
     // Copyright (C) 2010 - DIGITEO - Michael Baudin

     //
     // Check size
     // a can have any shape
     if ( s==[] ) then
       tf=(ones(a)==zeros(a))
       return
     end
     //
     // Check content
     // Nothing to do.
     //
     // Proceed...
     if ( a==[] ) then
       tf=[]
       return
     end
     //
     // Convert a into a column vector
     ma = size(a,"r")
     na = size(a,"c")
     a=a(:)
     //
     ns = size(s,"c")
     sp = s .*. ones(na*ma,1)
     ap = a .*. ones(1,ns)
     tf = or(ap==sp,"c")
     //
     // Convert tf into the same shape as a
     tf=matrix(tf,ma,na)
endfunction

This is an example:

-->     a = [
-->     7 35 14 86 76
-->     15 51 24 96 49
-->     35 40 46 35 93
-->     85 34 74 82 22
-->     ];

-->     s = [51 74 22 15 86]
  s  =

     51.    74.    22.    15.    86.

-->     tf = number_ismember(a, s)
  tf  =

   F F F T F
   T T F F F
   F F F F F
   F F T F T

Best regards,

Micha?l

Samuel,

Thank you! I looked at this document and it is exactly what I need! Unfortunately, from page 2 onward the text of the pdf file is not centered properly in the vertical direction. The margin at the bottom appears to be too large (about 2 inches) and there is no margin at the top --- there is text right at the top edge of the page. In other words, the text begins at the extreme top or the very top edge of the page. When I print the document the all the text in the top one inch of the page is truncated and is not printed. So there is missing text in the print out.

Could someone please regenerate the pdf file so that there is a one inch margin at the top of the page and also a one inch margin at the bottom of the page so that it will print out correctly?

Thank you.

Dean Parsons

Message-ID: <673016EEE3AE460DBE4981A45C7E3E45@optiplex745>

Is Scilab's remez function broken? When I try to use it it always returns an empty matrix [ ].

For example:

-->nc = 21;
 
-->ngrid=10240;
 
-->fg = linspace(0,0.22,ngrid/2);
 
-->fg = [fg linspace(0.25,0.5,ngrid/2)];
 
-->x = fg(1:ngrid/2)/128;
 
-->ds(1:ngrid/2)=ones(1:ngrid/2);
 
-->ds(ngrid/2+1:ngrid)=zeros(1:ngrid/2);
 
-->wt=ones(fg);
 
-->an=remez(nc,fg,ds,wt)
 an  =
 
     []

Are you using AcroReader or FoxReader.

I have sometimes problems with format. Acrobat Reader always works fine.

Hi Paul,

The status of the optimization is not good when the parameters are left 
to the default values :

-->neldermead_get(nm,"-status")
  ans =
maxfuneval

This means that the maximum number of function evaluations where reached 
before the convergence was attained. All we need to do is to increase 
the maximum number of function evaluations. In order to get even closer 
to the optimum, we must also increase the number of iterations.

nm = neldermead_configure(nm,"-maxfunevals",200);
nm = neldermead_configure(nm,"-maxiter",200);

Once done, I get :

-->xopt = neldermead_get(nm,"-xopt")
  xopt  =
     1.0035954
     1.0073491

This is quite a difficult case for Nelder-Mead's algorithm. The simplex 
has to go through a long curved valley before reaching the zone where 
the function begins to behave as a quadratic function.

Rosenbrock's function has only one global minimum, at x=[1,1]. The point 
x=[-1,1] is not a minimum.

This is easy to check with Scilab. First, let us define the function.

     function [f,G,H] = rosenbrock(x)
         f = 100*(x(2) - x(1)^2)^2 + (1 - x(1))^2;

         // Calculation of the gradient G vector
         G(1) = -400*x(1)*(x(2) - x(1)^2) - 2*(1 - x(1));
         G(2) = 200*(x(2) - x(1)^2);

         // Calculation of the Hessian matrix
         H(1,1) = -400*x(2) + 1200*x(1)^2 + 2;
         H(1,2) = -400*x(1);
         H(2,1) = -400*x(1);
         H(2,2) = 200;
     endfunction

We get at x= [1,1] :

-->[f,G,H] = rosenbrock([1,1])
  H  =
     802.  - 400.
   - 400.    200.
  G  =
     0.
     0.
  f  =
     0.

This means that the gradient is zero, implying that the first order 
conditions for unconstrained optimality are satisfied. Moreover, the 
eigenvalues of the Hessian matrix are positive, as shown below :

-->spec(H)
  ans  =
     0.3993608
     1001.6006

This implies that the local curvature of the Rosenbrock function is 
positive : x* is indeed a minimum.

Now, at x=[-1,1], we get :

-->[f,G,H] = rosenbrock([-1,1])
  H  =
     802.    400.
     400.    200.
  G  =
   - 4.
     0.
  f  =
     4.

The gradient is nonzero, which means that the first order optimality 
conditions are not satisfied at x=[-1,1]. Rosenbrock's function is a sum 
of squares.

Dear Micha?l,
 
I understand now ... effectively the -maxfunevals number has to be increase to 1000 to find the good solution ..
 
... May I suggest to add a warning in the macro either if the -maxiter parameter or the -maxfunevals one is reach so that the user is conscious the solution is not necessary optimized.
 
Thanks for your help
 
Paul

Hi Paul,

The status of the optimization is not good when the parameters are left to the default values :

-->neldermead_get(nm,"-status")
 ans =
maxfuneval   

This means that the maximum number of function evaluations where reached before the convergence was attained. All we need to do is to increase the maximum number of function evaluations. In order to get even closer to the optimum, we must also increase the number of iterations.

nm = neldermead_configure(nm,"-maxfunevals",200);
nm = neldermead_configure(nm,"-maxiter",200);

Once done, I get :

-->xopt = neldermead_get(nm,"-xopt")
 xopt  =
    1.0035954  
    1.0073491  

This is quite a difficult case for Nelder-Mead's algorithm. The simplex has to go through a long curved valley before reaching the zone where the function begins to behave as a quadratic function.

Rosenbrock's function has only one global minimum, at x=[1,1]. The point x=[-1,1] is not a minimum.

This is easy to check with Scilab. First, let us define the function.

    function [f,G,H] = rosenbrock(x)
        f = 100*(x(2) - x(1)^2)^2 + (1 - x(1))^2;
        
        // Calculation of the gradient G vector
        G(1) = -400*x(1)*(x(2) - x(1)^2) - 2*(1 - x(1));
        G(2) = 200*(x(2) - x(1)^2);
    
        // Calculation of the Hessian matrix
        H(1,1) = -400*x(2) + 1200*x(1)^2 + 2;
        H(1,2) = -400*x(1);
        H(2,1) = -400*x(1);
        H(2,2) = 200;
    endfunction

We get at x= [1,1] :

-->[f,G,H] = rosenbrock([1,1])
 H  =
    802.  - 400.  
  - 400.    200.  
 G  =
    0.  
    0.  
 f  =
    0.  

This means that the gradient is zero, implying that the first order conditions for unconstrained optimality are satisfied. Moreover, the eigenvalues of the Hessian matrix are positive, as shown below :

-->spec(H)
 ans  =
    0.3993608  
    1001.6006  

This implies that the local curvature of the Rosenbrock function is positive : x* is indeed a minimum.

Now, at x=[-1,1], we get :

-->[f,G,H] = rosenbrock([-1,1])
 H  =
    802.    400.  
    400.    200.  
 G  =
  - 4.  
    0.  
 f  =
    4.  

The gradient is nonzero, which means that the first order optimality conditions are not satisfied at x=[-1,1]. Rosenbrock's function is a sum of squares.

Best regards,

Micha?l

    Samuel,

    Thank you! I looked at this document and it is exactly what I need! Unfortunately, from page 2 onward the text of the pdf file is not centered properly in the vertical direction. The margin at the bottom appears to be too large (about 2 inches) and there is no margin at the top --- there is text right at the top edge of the page. In other words, the text begins at the extreme top or the very top edge of the page. When I print the document the all the text in the top one inch of the page is truncated and is not printed. So there is missing text in the print out.

    Could someone please regenerate the pdf file so that there is a one inch margin at the top of the page and also a one inch margin at the bottom of the page so that it will print out correctly?

    Thank you.

Moreover, the method that consists to type the "name_properties" in the

Hi,

Which version of Scilab do you use? which OS?

Do not hesitate to report a bug: http://bugzilla.scilab.org/

Hi everyone,

I am currently trying to convert my matlab code to Scilab that was using
Matlab Parallel Computing Toolbox.  Is it  is possible to do distributed
parallel computing in Scilab? If yes, how difficult is it to convert Matlab
code that was using Distributed Parallel Computing Server to Scilab? Any
comments are appreciated, even just  suggestions or websites that can help
are also appreciated.

Thank you

Hello,

If I understand your problem you have typed a script in scinotes and 
executed it, right?

First, output is usually done in the scilab console (the window that is 
opened when you launch scilab).
You can dock scinotes and the console in the same window.
I think that, starting from scilab 5.3, your configuration is saved so 
if you dock them one time it will be restored on the next startup.

Second you can set the execution verbosity level. See help("mode").

Generally, lines ending with a semi-colon (;) are not displayed.

Hope that helps.
Mathieu

Hello,

I don't know Matlab Parallel Computing Toolbox but I think that the 
closest solution in scilab is the PVM toolbox (help("PVM")). I have 
never used it but PVM is included in most clusters. I have no idea how 
hard it is to translate code.

Scilab 5.3 introduced the parallel_run function for multicore computers 
(help("parallel_run")).

I think that parallel computing is a main objective for scilab 6.

HTH,
Mathieu

You could also have a look to ProActive:

which includes a Scilab connector.

AFAIK, up to now, both PVM and parallel_run() cannot be used with Windows OS.

I don't know for PVM, but we use parallel_run() on Windows XP.
It works well for embarrassingly parallel tasks (aka running N times the 
same function with different inputs).

Hi,

I was looking for the same a year ago and found nothing.
So I quickly put together the function below to fill the area between 
two curves.
It is not exactly what you are looking for, but maybe it can help you 
hack your own solution.

Antoine


// Plot area between two curves
function [h,epoly,ey1,ey2]=BetweenCurves(x,y1,y2,varargin)
//
//      Plots two curves and fill the area in between
//
//      INPUTS:
//              x       vector (1,n) of horizontal coordinates
//              y1      vector (1,n) value of 1st curve y1(x)
//              y2      vector (1,n) value of 2nd curve y2(x)
//       -- optional inputs: pairs "keyword","value" --
//              "handle",h      handle to the graphic window to use
//              "axis",a      handle to the graphic axis to use
//              "foreground", colorid   id of the color to use for 
painting the area
//              "background", colorid   id of the color to use for 
curves stroke
//
//      OUTPUTS:
//              h       handle to the graphic window used
//              epoly   handle to the polygon that fill the area in between
//              ey1     handle to first curve
//              ey2     handle to second curve

//default values for optional argument
       hfig=-1;
       background=%nan;
       foreground=%nan;
// scan varargin for optional parameter pairs (they can appear in any order)
    for i=1:2:length(varargin)
       keyword=varargin(i);
       value=varargin(i+1);
       select keyword
          case "handle" then
             hfig=value;
             scf(hfig);
          case "axis" then
             axis=value;

          case "foreground" then
             background=value;
       end
    end
// special treatment for handle (aka hack alert)
    if typeof(hfig) ~= "handle" then
       hfig=scf();
    end
    h=hfig;
    scf(hfig);
    xfpoly([x,x($:-1:1)],[y1,y2($:-1:1)]);
    epoly=gce();
    plot(x,y1);
    ey1=gce();
    plot(x,y2);
    ey2=gce();
// background setting
    if (~isnan(background)) then
       // optional background specified
       epoly.background=background;
    else
       // default background
       epoly.background=color("gray87");
    end

Subject: CallScilab under Windows
Message-ID: <LKECIGCCKNOMMCKAGNOAIEFLDDAA.Mike@Page-One.Waitrose.com>

Hi,

Has anyone managed to get CallScilab to work under Windows?  The information
on the web page is mainly for Linux and is hard to convert.

I am using a pre-compiled version of Scilab 5.3.0 under Windows XP and have
built the example C source code (from
http://www.scilab.org/product/man/call_scilab.html) with Visual C++ Express
2010.

I got the include files from the directories:
C:\Program Files\Scilab-5.3.0\modules\call_scilab\includes
C:\Program Files\Scilab-5.3.0\modules\api_scilab\includes
C:\Program Files\Scilab-5.3.0\modules\core\includes

and the lib files from:

C:\Program Files\Scilab-5.3.0\bin\api_scilab.lib and call_scilab.lib

I have C:\Program Files\Scilab-5.3.0\bin in the Path so that the DLLs can be
located at run time.

The example builds OK, but there are two warnings:

1. The example includes stack_c.h, which is deprecated.  I changed it to
api_scilab.h instead.

2. The third parameter of StartScilab is given as NULL, but the prototype
has this as an int (although the documentation says int*).  I changed it to
0 which shouldn't make any functional difference.

That got an error-free and warning-free build.

When I run the code, the call to StartScilab generates an error:

"Impossible to read <path to my executable>\etc\jvm_options.xml"

Should there be a path or environment variable setting for this?  I have an
environment variable SCI set to C:\Program Files\Scilab-5.3.0.

I copied the directory C:\Program Files\Scilab-5.3.0\etc to <path to my
executable>\etc so that I would have a default jvm_options file and the
error changes to:

"Scilab cannot create Scilab Java Main-Cass (we have not been able to find
the main Scilab class. Check if the Scilab and thirdparty packages are
available)."

Any suggestions as to where I go from here.  It looks like I am missing some
step in the configuration.

Thanks,
Mike.

Objet?: [scilab-Users] CallScilab under Windows

Hi,

Has anyone managed to get CallScilab to work under Windows?  The information
on the web page is mainly for Linux and is hard to convert.

I am using a pre-compiled version of Scilab 5.3.0 under Windows XP and have
built the example C source code (from
http://www.scilab.org/product/man/call_scilab.html) with Visual C++ Express
2010.

I got the include files from the directories:
C:\Program Files\Scilab-5.3.0\modules\call_scilab\includes
C:\Program Files\Scilab-5.3.0\modules\api_scilab\includes
C:\Program Files\Scilab-5.3.0\modules\core\includes

and the lib files from:

C:\Program Files\Scilab-5.3.0\bin\api_scilab.lib and call_scilab.lib

I have C:\Program Files\Scilab-5.3.0\bin in the Path so that the DLLs can be
located at run time.

The example builds OK, but there are two warnings:

1. The example includes stack_c.h, which is deprecated.  I changed it to
api_scilab.h instead.

2. The third parameter of StartScilab is given as NULL, but the prototype
has this as an int (although the documentation says int*).  I changed it to
0 which shouldn't make any functional difference.

That got an error-free and warning-free build.

When I run the code, the call to StartScilab generates an error:

"Impossible to read <path to my executable>\etc\jvm_options.xml"

Should there be a path or environment variable setting for this?  I have an
environment variable SCI set to C:\Program Files\Scilab-5.3.0.

I copied the directory C:\Program Files\Scilab-5.3.0\etc to <path to my
executable>\etc so that I would have a default jvm_options file and the
error changes to:

"Scilab cannot create Scilab Java Main-Cass (we have not been able to find
the main Scilab class. Check if the Scilab and thirdparty packages are
available)."

Any suggestions as to where I go from here.  It looks like I am missing some
step in the configuration.

Thanks,
Mike.

Hi Allan,

Thanks for the suggestion - I didn't see that example.

I couldn't get it to build and run as supplied.  I had to convert it from
VC9 to VC10 and the conversion failed for some reason.

So I made a new project with the same source file, guessing your project
settings by reading the vcproj file.

It looks like I'm missing a library, as I get 3 undefined symbols:
_creadmat_
_cmatptr_
_cwritemat_

Where can I find those entry points?

Thanks,
Mike.

Hi,

When I type "help plot2d", I have a hard time reading because the font is too small for my old eyes. Also, in the examples, the background color and keywords colors also make it difficult for me to read.

Is there a preference I can set to make the font larger and turn off the background color?

There is no way to do that for the moment... A workaround is to use the

Dear scilab community,

I continue to have a problem that I already brought forward to this list a while ago. It manifests itself in repeated crashes of scilab after plots of graphics. It leaves behind a log file that starts with
# A fatal error has been detected by the Java Runtime Environment:
#
#  SIGSEGV (0xb) at pc=0x00fa2416, pid=2016, tid=41278320
#
# JRE version: 6.0_18-b07
# Java VM: Java HotSpot(TM) Server VM (16.0-b13 mixed mode linux-x86 )
# Problematic frame:
# C  [+0x416]  __kernel_vsyscall+0x2
Previously I was told to upgrade my graphic card drivers. I did that, but the problem persists. I'm now starting to suspect that I have a hardware problem with a faulty graphics card. Is there a way to confirm this suspicion?

Thank you and best regards,
     Peter

Is the file *.bin.i686.linux.tar.gz for Linux 32bits or 64bits ?

If you are using ATOMS, it will get Linux modules for you.

If you installed them yourself, it depends. If it is a module only with
macros, it should work out of the box. If it contains C or Fortran code,
you will have to rebuild it.

If you are moving to Ubuntu Linux, may I suggest that you have a look at the *.deb package from Ubuntu packages (http://packages.ubuntu.com/maverick/scilab).  This is not the latest version (Version 5.2.2), but it will build automatically on your machine (64 or 32 bit) with all of the dependencies met.  I am of the opinion that one should work with stable versions of any software package when one is trying to do real work.  As noted by others, any code you may have written in c or fortran will have to be re-compiled, but Ubuntu comes with excellent c and fortran compilers...

It works, for me (scilab 5.3.0-b3 / winXP)
Has the last instruction -- xrects(..) -- actually been performed
(with a ending carriage return)?
Otherwise, it may comes from a restriction of you graphic driver.

Samuel

OK, the only problem is the color index 34 you have chosen.
By default, it is not defined: only 32 colors are defined
in the default colormap of a figure.
So, either you may choose a predefined color <= 32, or you
may define your own one. Examples:

xrects(rects,30*ones(xx))
xrects(rects,color(56, 10,40)*ones(xx))

It has worked for me because i defined and used other colors
for some other work, before trying your example.

Regards
Samuel

Samuel,

Thanks, that worked. You can see how new I am to Scilab.

I am using SciLab 5.2.2 for one of my classes as instructed by my teacher and when I use the plot command it exits the programs, I have tried the Windows 7 32-bit as well as the 64-bit version of SciLab and both do the same, my laptop is running on Windows 7 Home Premium 64-bit. I know that I'm using the plot command correctly as the same command works on my desktop please let me know what steps can be taken to fix this. I'm attaching a video so show you what exactly happens when I try to plot a function.

Message-ID: <E6E72B44-3852-4DDB-9147-00E114DD9590@free.fr>

 1) On iMac 20 po (beginning 2006), Mac OS X 10.6.6 Snow Leopard, Intel Core Duo, 32 bits, Java SE6 32 bits 1.6.0_22-b04-307 : Scilab 5.2.2 works well but Scilab 5.3.0 does not want to start, in that case the Console display :
"19/01/11 00:59:20	[0x0-0x313313].org.scilab.modules.jvm.Scilab[7700]	/Applications/scilab-5.3.0.app/Contents/MacOS/bin/scilab: line 535: /Applications/scilab-5.3.0.app/Contents/MacOS/bin/scilab-bin: Bad CPU type in executable".

 2) On MacBook Pro 15 po (december 2010),  Mac OS X 10.6.6 Snow Leopard, Intel Core i5 ou i7, 64 bits, Java SE6 32 bits 1.6.0_22-b04-307 : both Scilab 5.2.2 and 5.3.0 work very well.

 3)On the two Mac after starting the functional versions, the Console display :
"21/01/11 17:35:44	[0x0-0x3f93f9].org.scilab.modules.jvm.Scilab[10305]	JavaVM: requested Java version (1.5) not available. Using Java at "/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home" instead."

 My question is : is Scilab 5.3.0 able to work on a 32 bits Mac, or on a 64 bits one only ? If so this point should be written in the "system requirements" for each Scilab OS X version.

  I tried to report this as a bug : too difficult, long, complicated? chinese torture ! Made for developers not for simple users... I'll never try again.

Dear All,

 

For some times I'm testing Scilab macros for optimization purposes ;
"optimization" has to be intended here as an inverse method for fitting
parameters (i.e. so that finite element analysis fit test measurements).

 

I tested basic macros such as fminsearch for unbounded fitting as well
as Nelder-Mead one for bracketed parameters fitting. Basically the "cost
function" is the normalized Sum of the Square errors SSE from the FEA to
the measurements.

 

In my FEA's the variables can be material parameters, spring
stiffness's, damping ratio and so on : the simplex method is well
adapted since the former variables are not analytically described in the
cost function and since it's not necessary to calculate the gradient
vector nor the Hessian matrix ...

 

 

If this method is robust nevertheless it remains rather slow !

 

 

Is there a way or another macro I can use to reduce the number of loops
and the time consuming consequently ?

 

Nota : I was thinking in OPTIM macro but from my understanding the cost
function need to be twice differentiable at least  (for the Gradient and
the Hessian ) i.e. analytically link to the parameters ... isn't it ?

 

Thanks in advance for any advice (for a better understanding)

 

Paul

Dear all,

I'm looking to extract from a matrix "A" one value for each line. The column
positions of the value to extract would be given by a vector "c".

Here is an example:
A = [ 1 2 3 ; 4 5 6 ; 7 8 9 ; 10 11 12 ; 13 14 15 ]

c = [ 3 ; 1 ; 1 ; 2 ; 3 ]

How can I get the resulting vector [ 3 ; 4 ; 7 ; 11; 15 ] ?

I'm currently using a loop which is obviously a time expensive solution with
large matrix.
Any ideas to get it more efficiently?

Thanks,


Jean-Damien

Dear JD,

I will not take the time now to get into detail... But I think you should use Matlab/Reshape ie Scilab/Matrix, work with all your data in a row and subsequently transform your indices to keep.

Hi,

I guess there are lots of ways to do it - not sure what's most efficient.
How about

-->diag(A(1:length(c),c))
 ans  =

    3.
    4.
    7.
    11.
    15.

That's at least quite compact...

You could try a genetic-type algorithm, such as differential evolution. 
I don't think there's a scilab implementation (at the very least, I 
don't think there's one distributed with scilab).

See information (and code for several ports) here:
http://www.icsi.berkeley.edu/~storn/code.html

Implementing the basic algorithm in scilab (in any language for that 
matter) is easy and quick.

There are several references on that page. I recommend the first few 
chapters of "Differential Evolution - A Practical Approach to Global 
Optimization" by Ken Price, Rainer Storn, and Jouni Lampinen.

Otherwise, search for algorithms such as 'simulated annealing'. I've 
heard good things although I've lately been helping colleagues, who 
relied on that algorithm for some minimization problems, migrate to DE 
as a potentially more robust and efficient algorithm.

Good luck,

Charles

Your problem is probably due to a problem with your graphic driver
(especially if you run an Intel HD graphic card).

We are aware of the issue and we are working on it.

Hi,

i am trying to compile scilab on Ubuntu 10.04 (and also on on Ubuntu 10.10)
and I manage to configure/make/make install which is good but when I want to
start the help Scilab gives an error message

 !--error 10000
help: help file(.jar) is not installed.
at line 42 of function help called by :
help();
while executing callback

So I go to my scilab folder and do make doc but I get the same error! What
am I doing wrong?

Problem with fmincon:

It says the function fmincon_checkrhs not defined!

I downloded it from ATOMS! Do I have to difen fmincon_checkrhs separately?

Thanks

What is saying "make doc" ?

Are you sure you have all dependencies ?
(apt-get build-dep scilab if not)

Thanks for your answers.
I like the diag(A(:,c)) solution (however it's slower than the first
proposed solution).

To continue this discussion, actually my initial wish was to do the same
thing with a structure.
Let's say I have the structure "st" with a field "f" such as:
st(1).f = [1 ; 4 ; 7 ; 10 ; 13];

st(2).f = [2 ; 5 ; 8 ; 11 ; 14];

st(3).f = [3 ; 6 ; 9 ; 12 ; 15];

and the same vector than previously
c = [ 3 ; 1 ; 1 ; 2 ; 3 ];

I want to extract the vector such as for the index i, extracted value =
st(c(i)).f(i)
and so get the same result than previously [ 3 ; 4 ; 7 ; 11; 15 ]


Do you have any idea to do it without having to reconstruct a matrix (such
as [st(1).f st(2).f st(3).f]) ?

Thanks,

JD

Hi Paul!

Before trying such approaches, if you cannot (or don't want to)
compute gradients and hessian, you may let Scilab approximate them
numerically thanks to the "NDcost" function. It generally works very
well so I strongly recommend it before even thinking using some
stochastic methods (which are not bad but should not be used when not
necessary and I guess you don't need them in your case).

Note that they are plenty of fully deterministic heuristics to
optimize without gradients (not even numerically approximated), which
are too often forgotten and often even not included in optimization
packages. As for all methods they are always some problems, but it
solved quite efficiently many optimization problem in the past and not
all optimization problems are tough or are worth writing 30 pages of
calculus to get an analytical expression for the gradient of the cost
function...

Anyway... have fun with NDcost!

Regards
Nicolas

Hi,

Indeed, the Nelder-Mead algorithm is rather slow, as can be expected 
from an algorithm which does not rely on neither the gradient nor the 
Hessian (or any approximation to it).

You can use the optim function to solve your problem. In the optim help 
page :

http://www.scilab.org/product/man/optim.html

search for "Example: Optimizing with numerical derivatives".

The function does not have to be analytic : the only thing that is 
required is that the function can be evaluated.

Of course, the function should be smooth for the function to work better.
  * If f and its gradient are continuous, optim with the quasi-Newton 
and the limited BFGS algorithms should work well (i.e. try the "qn" and 
"cg" options).
  * If f is discontinuous, only Nelder-Mead can work (but is likely to 
have some problems to converge).
  * If f is continous but its gradient is discontinous, you may try the 
"nd" option. It is a special algorithms for functions in this class 
(e.g. min max_i f_i). Lemar?chal is an expert on this topic.

Try it and you will see !

Best regards,

Micha?l

I do not suggest to use NDcost, which should not have been integrated 
into Scilab anyway.

Indeed, this macro has only 2 lines where the first one calls f, and the 
second one calls derivative. We can customize the cost function directly 
ourselves, which has the major advantage of being able to fully 
customize the options of the derivative function. Moreover, we can use 
the full potential of the printing options provided by the optim 
function, which is not possible with NDcost.

Hi Micha?l,

 

Let me saying first (if necessary) I've good results using simplex routines (either fminsearch macro or Nelder-Mead one).

 

It is well known (and mentioned in the literature for example) that this algorithm is robust but slow ... but in some cases it's the last solution (for not saying the last chance) !

 

 

Basically the purpose is to increase the convergence (and the optimization total duration) ... especially when each FEA (= 1 loop) need more than one hour !

 

Commonly I noticed several decades (for not saying hundreds) of loop with Nelder-Mead

 

Paul

Hi Norm,

Sorry if this response is too late for you, but it may help somebody else...

I came across your post while looking for help on another issue related to
plotting with SendScilabJob.  Here is some example code that runs the
plotting in a separate thread under WinXp.  It works for me and I think it
would do what you wanted.  Sorry it's a bit short on comments ;-)

To build this, you need to also include the /include directories from:
SCI/modules/call_scilab
SCI/modules/api_scilab
SCI/modules/core

You also need to set the library path to include SCI/bin and include the
libraries:
api_scilab.lib
call_scilab.lib
MALLOC.lib
LibScilab.lib

When running, /SCI/bin needs to be in your path so Scilab can find the DLLs.

HTH.
Mike.

Subject: [scilab-Users] Question on using plot in call_scilab module


Hi,

I'm using the call_scilab module to access scilab functions from within
a C program.  I'm using MS Visual C++ 2008 on MS Vista.

Everything that just writes its output to the console works ok.  However
when I use the scilab plot command
      SendScilabJob("plot(x,y, style);")
I find that the plot window freezes and the plot menu options are
unavailable unless I run the following loop: -
    while( ScilabHaveAGraph() )
    {
        ScilabDoOneEvent();
    }
Of course this loop stops my program from doing anything else.

My question:
I believe this problem arises because everything is operating in a
single thread.  Is there a way to make the plot command start out in a
separate thread so that it can still monitor for user events such as
mouse clicks while the rest of my program continues.

thanks,
Norm

Managing Scilab graphics and Scilab windows from call_scilab & Javasci
v2 is something I would like to improve in the next releases but I am
still unsure on the right way to implement this...

If you have ideas, I would be happy to hear them.

Subject: Root finding
Message-ID: <55A12CBC06A8C9459DCE0BBEF8122FDC0498B0D2@exchsrv.AUXITROL1>

Dear all,
 
is it a stupid question in asking why the condition herebellow leads to
an error ?
 
Nota :  
- I just want to keep the integer values resulting from the root finding
... 
- (if + r_) leads to en error while the formula works T2_ = T0_ / (1 +
0.5*(gamma_ - 1)*r_(1)^2) ??


Another (stupid) question : 
-  is it possible to perform a root finding with real exponents instead
of integer ones ? if so how ?
- the exponents typically look like [ 0.5*(gamma_ + 1) / (gamma_ - 1) ]:

 
Thanks everybody for (previous and futur) advices
 
Paul

x = poly(0,"x");
p = 1 + coef_1*x + coef_2*x^2 + coef_4*x^4 + coef_6*x^6 ;
r_ = roots(p);

if ( r_(1) < 1) then
    Mach2 = r_(1);
    Mach3 = r_(2);
else
    Mach2 = r_(2);
    Mach3 = r_(1);
end
 
// Before the sonic col
P2_ = P0_ / (1 + 0.2*r_(1)^2)^3.5;
T2_ = T0_ / (1 + 0.5*(gamma_ - 1)*Mach2^2);

// After the sonic col

T3_ = T0_ / (1 + 0.5*(gamma_ - 1)*Mach3^2);

Hi!

Well I agree that NDcost is not very optimal and we could do better...
but I would not remove it from Scilab because it is just extremely
simple for the user to call optim(NDcost(... )) and works quite good
for easy optimization problems. Part of the philosophy behind software
like scilab or matlab is to provide very simple tools for engineers,
and to give them the possibility to go a lot further if required. So I
would simply let the users choose whether they want to use NDcost or
not and possibly give them enough information in the documentation in
order them to make the right choice.
Note that I am of course talking here about the functionality provided
by NDcost, not about the way it is implemented presently.

Nicolas

I should have been more precise. I didn't think there was an 
implementation of 'differential evolution' in scilab, though I knew at 
least one type of genetic algorithm was in there. Indeed, from a cursory 
look at the help of optim_ga, all the basic pieces are there except, as 
far as I can tell, for the mutation algorithm. It wouldn't be that hard 
to write up the mutation algorithm and get DE in there, though.

Cheers,

Charles

Hi,

I'm new to scilab and I would like to solve equations to certain variables,
like matlab does it with solve('equation', variable).
But I allways want to learn something and not only using the result. So is
scilab able to present every intermediate step so that I could transpose it
manually on my sheet of paper?

And if so how do I do that?

Best regards,

Dear Sir or Madam,

I've just downloaded the new Scilab 5.3.0 from you page, but it  
doesn't run. When I double click on the icon to start the program, a  
message occurs that the program was unexpectedly closed.
The whole error description is attached below.

I use the mac OX 10.5 with 2.1 GHz Intel Core 2 Dou and 2 GB DDR2 SDRAM.

If you have any ideas how to solve this problem and get the program  
started I would be very glad.


Best regards

Hi,

I checked the last fmincon package v0.3 in Scilab 5.3.0 and all the 
examples run fine.

The unit tests also run:

-->atomsTest("fmincon")
    TMPDIR = C:\Users\baudin\AppData\Local\Temp\SCI_TMP_7960_

    001/005 - [SCIHOME\atoms\fmincon\0.3-1] fmincon_basic...........passed

Can you provide the example which fails ?

Hi,

In the current solve function, we cannot display intermediate steps. 
Notice that Matlab's solve can solve nonlinear equations, while Scilab's 
solve can only solve linear systems of equations.

As this is a macro, we can edit this function with

edit solve

 From there, it is easy to insert a couple of "disp([a b])" to display 
the intermediate steps.

Best regards,

Micha?l

Subject: feedback on OPTIM macro
Message-ID: <55A12CBC06A8C9459DCE0BBEF8122FDC0498B0DE@exchsrv.AUXITROL1>

Dear All,

 

I 'm currently testing the optim macro in Scilab/FEA (external) solver FEA  and I would like here to share some feedbacks ...

 

First of all regarding the documentation, I noticed :

 

 

 

A) 'gc' and bounds use

'qn' -> BFGS algorithm

'gc' -> conjugate gradient

'nd' -> ?

>From the documentation  "Note that the conjugate gradient solver does not accept bounds on x. "

Whereas the example "Scilab function" uses bounds with 'gc' ... ???? 

// Upper and lower bounds on x and setting up the algorithm to 'gc'
[f,xopt,gopt]=optim(cost,'b',[-1;0;2],[0.5;1;4],x0,'gc')

 
B) bounds violated
I tried several syntaxes for the bounds (with or without the dot coma i.e vector or its transposed) and all the time I noticed negative values of x ...
 [fopt,optimized_parameters] = optim(optimization_BFGS,'b',[0;0],[2;2],initial_parameters','ar',nap,iter,epsg,imp=-1);
 Is there something wrong ?
 
 B) derivative use
 I noticed the strong influence of the h parameters (for the step) as well as the order parameter (order 2 by default) :
?       If h is too small ? a lot of evaluations
?       If h is too high ? loops quickly stop far from the optimized values 
 order is essentially used for the function evaluation ; I tried different values of "order" thinking in a better function evaluation (for a better gradient calculation) ... but the default value seems to be the best one.
 
  
C) Other algorithms
 I tested on a basic Rosenbrock function other order 0 method such as Genetic Algorithm or Simulated annealing but many function evaluations are necessary (more than a thousand) .... but probably the parameters have to be optimized themselves (Population size / number of mutations and so on ) ... 
 since one evaluation need one FE modelling (i.e. the longest calculation duration), I'm not sure they are the most efficient for my application ... finally the Nelder-Mead method is probably one of the best !
 
 
Regards
 
Paul

Subject: eps export unusable with psfrag
Message-ID: <4D46C569.9000709@utc.fr>

Hi all,

it seems that the new eps (an also others) export transforms fonts glyphs
to paths, so that it is impossible to psfrag to recover strings in the eps.
Is there a workaround ?
I know that latex rendering is now possible in scilab graphic text, but
sometimes you have to scale a graph without scaling also the text.

For now, Scilab 5.3.0 is not available under Mac OS X 10.5. 
It is "normal". Apple pushed an important update in their Java packaging

Scilab is built on (used also under GNU/Linux and Windows)
