Hello Tim,

        Thanks for suggestion. I will not be able to send the whole xcos
file because of proprietary reasons. I am trying to trim the blocks up and
see if the problem is with any particular block.

        To give you a big picture, I am actually mathematically modelling a
PLL. In this when I am trying to connect the feedback path from the VCO to
the PFD, the error message is coming.

        Thanks again for replying. I will reply soon once I find something
on this.

With Regards.

Message-ID: <1441117215316-4032767.post@n3.nabble.com>

Dear all.
Save the attached file in current diorectry and run the following script.
******
load('test.dat');
disp(x);//x contains 0.1 as the 3rd elemnt.
disp(y);//y is 0.1
z=find(x==y);
disp(z)//failure because z returns [] instead 3.

****
Since x contains y as the 3rd element ,
find(x==y) should return 3.
But it returns [].
Is there any error in my script or is this just a bug of scilab6?

Best regards.

Hello,

You forgot to attach the test.dat file.
But take care that two different values can give the same display.

To check it you can compute x(3)-y

Hello Serge Steer 

As you suggested, x(3)-y = - 1.388D-17.
I must improve to genarate values of x.
Thanks a lot.

Best regards.

Subject: [Scilab-users] HDF5 file : how to access HDF5 compound elements
Message-ID: <55E6E583.2090908@laas.fr>

Hi all,

Almost everything is in the title: I am trying to load in scilab the 
content of an HDF5 file and some of the datasets are of type compound of 
array of variable length:

h5dump(xyg)
DATASET "XY Graph" {
    DATATYPE H5T_COMPOUND {
             H5T_VLEN { H5T_IEEE_F64LE } "elem1";
             H5T_VLEN { H5T_IEEE_F64LE } "elem2";
    }
    DATASPACE SCALAR
    STORAGE_LAYOUT {
       CONTIGUOUS
       SIZE 0
       OFFSET 18446744073709551615
    }
    DATA {
    (0): {
       (),
       ()
    }
    }
}


How can I access elem1 and elem2?
I tried things like:
     xyg.data
     xyg.elem1
     xyg.data.elem1
     xyg.compound.whatever
without success...

Any clue?

Cheers,

Antoine

PS: I can give you an example hdf5 file if needed, but it's quite big!

Hi Antoine,

Probably something like:
d=xyg.data(0);
d.elem1
d.elem2

Please provide me a file (you can send it to me privately), it could 
have some bugs.

Best regards

Hello,

I am posting the xcos file which shows the error. Thanks Tim, your trick
worked out in identifying the the exact block in which the error existed.
But the problem is still persists. Please find the block and suggest
something regarding.

With regards,

Thanks Calixte, it's almost what I was looking for ( data(0) -> data(1) ).
I think that my hdf5 file is not containing what I was looking for and 
it might even be corrupted!
It seems to efficiently crash scilab 6.0.

I'll fill a bug.

Hi Fran?ois,

Is there a decision on the threading model yet?

Many thanks, best wishes,

Hi, Fran?ois

Thanks for your reply.

I tried to install the latest one  according to the following instruction of
the readme file incleded in the package.

       scipver = "X.YY";
        atomsSetConfig("offLine","True");
        atomsInstall(<MYDIR>+"/scipad-"+scipver+"-Scilab5.zip");
        if ~exists("atomsinternalslib") then
          load("SCI/modules/atoms/macros/atoms_internals/lib");
        end
        execstr("exec("""+atomsGetInstalledPath(["scipad"
scipver])+"/builder.sce"",-1)");
        atomsLoad("scipad");

But the installation failed with the following message.

-->exec(MYDIR+'\installScript.sce', -1)
 !--error 10000 
atomsExtract: The file MYDIR+"\scipad-5.5.2-Scilab5.zip" does not exist or
is not read accessible.

How can I fix this problem?

Best regards

The installation instructions are both in the package itself and here:

http://sourceforge.net/p/scipad/wiki/Installation/

Did you follow them carefully?
Specifically, in the commands to type (or paste) in Scilab you have to 
replace the string <MYDIR> by the folder name where you saved the 
downloaded package, and X.YY by the Scipad version number.

Regards,
Francois

What package did you download? You seem to confuse the package for 
Scicoslab with the package for Scilab.

For Scilab, you should have downloaded scipad-8.73-Scilab5.zip 
<http://sourceforge.net/projects/scipad/files/scipad-8.73/scipad-8.73-Scilab5.zip/download> 
and not scipad-8.73-Scicoslab.zip 
<http://sourceforge.net/projects/scipad/files/scipad-8.73/scipad-8.73-Scicoslab.zip/download>

A downloaded from the download button in the page you suggested in the first
reply.
Actulally it was the package for Scicoslab as you said.
I downloaded the right one from the 'files tag'  and I succeeded to install
it.
Thanks a lot.

But I have another problem.
The corruption of text happens as the attached image.
I use the Japanese language and of course choose options-locale- 'japan'.

Is there any way to fix it?

This message contains only:

I have learned a bit of Japanese but not enough to understand what is 
wrong with your snapshot?
Are you about the menu items, which are still in English?
For me that is working (see attached snapshot).

Francois

The left one of the above image is the display of same script with Scinote
and the ridht one is that with Scipad.
I am not sure non-Japanse can see the difference.
Left one display Japanese rightly but Right one doesn't.

Menu items are Japanese.
Maybe the cause of error is due to  bad choice of an encoding type.
Scinote has the menu item 'option-file encoding' which choose unicode utf-8.
Is there a corresponding item in Scipad?

Best regards

Fujimoto

Yes of course, Scipad supports text encodings, and especially utf-8.

You can find this setting in the options -> file open/close settings -> encoding menu (sorry, this may not be completely accurate, I'm not in front of a computer and I'm quoting from memory only).

Hi,Fran?ois

The problem is fixed.
The file encoding 'cp932' was chosen and after utf-8 is chosen it display
rightly.

Thanks a lot for your help.

Best regards

I expected the following script to generate?linearly spaced vectors x1,x2 and

But x1(3),x2(2) and x3(15) are slightly different values from expected

This phenomena happens with both Scila5.5.2 and Scilab 6.0.0 alpha.

Hello,

The error magnitude seems to smaller than the default machine precision for Scilab double floating numbers (%eps = 2.220D-16) .

There are some Scilab packages for arbitrary precision (MPScilab, MPAT, Xnum,...), you may want to check them out.

Regards,
Rafael

Hello,

Let me explain why I want to get exact values.
There is the following line in my script.
x_i=find(x1==0.12)
I suppose  it returns 3 but actually it fails to return 3 due to the error.
So I modified that line into
x_i=find(abs(x1-0.12)<10^-10)
This work well only when x1 contains a single value near 0.12.
But sometimes x1 contains 0.15 and 0.15000000002 depending on the way of
generation of  x1.
(The example  of the topic is a simple version of the more complex actual
script.)
In this situation 'find(abs(x1-0.12)<10^-10)' returns two values and my
script doesn't  work.

This is why I want to exact values.

Can I get exact value by using  (MPScilab, MPAT, Xnum,...)?

Best regards




 fails to return 3.

Hello,

you may use either:

x1 = (10:20)/100;
disp(x1(3)-0.12)

or
x_i = find(clean(x1-0.12)==0)

Subject: [Scilab-users] Plot command line specification compressed to a

Message-ID: <55EC4D8F.7020600@hslmg.de>

I would like to replace the line specification in a plot command by a 
variable that can be used as an function input argument.  E. g. the line

plot([1:4],[1:4], 
'LineStyle','none','Marker','+','MarkForeground',[255;215;0]/256)

should be replaced by

plot([1:4],[1:4],LS)

How should LS be constructed?

Kind regards

Jens

p.s.

To avoid hints to work arounds: I'm aware of gca(), gce(), parents and 
children. This is not what I aim at.

As a list:

Subject: [Scilab-users] [ANN] Scipad-8.74
Message-ID: <55EC5CE7.6050509@free.fr>

ANNOUNCE: Scipad version 8.74
=============================

A new version of the Scipad text editor for Scilab and Scicoslab is 
available.


CHANGES SINCE PREVIOUS VERSION
==============================

NEW OR IMPROVED FEATURES:

  * Re-ordered the Help menu items

  * Added a "System encoding" entry in the Encoding sub-menu

  * Clamped the width of the reformat lines window to a maximum to avoid
    huge temporary widths, especially during width changes - Added an
    horizontal scrollbar to the preview area

  * Display of margin showing modified lines is a saved preference

  * Small speed up of Scipad startup

  * Better performance with typing and clicking by distinguishing buffer
    switches and running just what is needed to keep the display 
up-to-date

  * Added console show/hide toggling in the system menu (on Windows only)

  * Allowed some default bindings for the text widget to be used in the
    find in files results dialog and text box, such as up/down, page
    up/down

  * Added tooltips showing the contents of the find/replace comboboxes
    when they are truncated by the available display space

  * Incremental find saves history of what was searched previously

  * Added some known file extensions to the file dialogs

  * Added splitting handles on top and on the left of scrollbars, to
    split the display into tiles (mouse button 1) or to split a file into
    several views (mouse button 2)


FIXED BUGS:

  * Fixed Tcl error poping up after closing Scipad running in Scicoslab

  * Fixed bug: After using find/replace, clicking close to the end of a
    long line did not move the cursor to the desired place but closer to
    the beginning of this line

  * Fixed missing re-use of the find in files results window when several
    such windows were opened and one of them got closed

  * Fixed error when moving the y scrollbar in the reformat lines window

  * Fixed cursor seen inside the selection when clicking on it, moving
    the mouse, and releasing the button while still hovering above the
    selection

  * Fixed error when launching "Join selected lines" command with no
    selection

  * Fixed bug with reformat lines producing wrong result when the first
    line has leading spaces

  * Fixed incorrect behavior when cancelling a request for replace all

  * Fixed unexpected scrolling of the text area when using the mouse
    wheel in an opened combobox of the find/replace dialog

  * Fixed bug: wrong focus restore after closure of comboboxes

  * Fixed unexpected encoding switching of the current file when opening
    an xml file for which encoding detection was successful



WHAT IS SCIPAD ?
================

Scipad is a powerful editor and graphical debugger for programs 
written in Scilab language. It is a mature and highly configurable 
programmer's editor, including features like syntax colorization, 
regexp search/replace, parentheses matching, logical/physical line 
numbering, peer windows, line and block text editing, and much more. 
Scipad can be used along with Scicoslab or Scilab, but even as a 
standalone text editor. Used as internal Sci(cos)lab editor, it 
interacts tightly with the interpreter, allowing:

  - Scilab code execution control
  - conditional breakpointing
  - variable retrieval and tooltip display
  - Scilab help lookup
  - access to source code of Scilab library function
  - control of Scilab facilities for Matlab code and creation of
    help documents
  - and much more

Scipad also includes basic Modelica and XML syntax colorization; it is 
currently localized in 13 languages and further localizations can 
easily be added. Scipad is entirely written in Tcl/Tk and Scilab 
language. It has been tested and developed under various versions of 
Windows and Linux.


WHERE CAN SCIPAD BE FOUND?

Message-ID: <BAY169-W1015FF9A38BB2CCF3EA18DAEE550@phx.gbl>

Hi:

I was wondering how does scilab to generate a cos diagram from scs_m...

For example, i have a diagram whose scs_m is:

 scs_m  =
 
wpar = [600,450,0,0,600,450]
title = "Controller"
tol = [0.000001;0.000001;1.000D-10;100001;0;1;0]
tf = 30
context = ["A=[-.3,3,1;0,0,2;0,0,0];B=[1;2;3];C=[1,1,2;0,2,3];D=0;x0=[-2;1;2]";"K=ppol(A'',C'',-.7*ones(x0))'';";"L=-ppol(A,B,-.7*ones(x0));";""]
void1 = []
options = tlist(["scsopt","3D","Background","Link","ID","Cmap"],list(%t,33),[8,1],[1,5],list([5,1],[4,1]),[0.8,0.8,0.8])
void2 = []
void3 = []
doc = list()
1     CLOCK_f
2     RAND_f
3     SUMMATION
4     SPLIT_f
5     CLKSPLIT_f
6     DEMUX
7     GAIN_f
8     SUM_f
9     SPLIT_f
10    SUPER_f
11    SUPER_f
12    SUM_f
13    CSCOPE
 
i would like to be able to generate the same diagram with that information by myself, to open it with a custom application... is the scs_m enough? is there any documentation from where to start?

Thanks

Subject: [Scilab-users] Identifying parameters of a multy frequency damped
	oscillation
Message-ID: <55ED827C.1070008@hslmg.de>

Hi Scilab users,
I  want  to  analyse  a  microphone  recording  of  the  sound  of  a  bell  or  gong.Given  ia  the  equidistantly  sampled  sound  pressure  y(t)  after  a  stroke  for  10  s.

The  ansatz  

y=sum(   A_i*exp(-d_i*t))*cos(2*%pi*f_i+alpha_i)   )   for i=1,2,...5 or more

is  assumed  to  approximate  the  signal  where  A_i,  d_i,  f_i,  and  alpha_i  are  the  unknown  amplitudes,  danping  factors,  frequencies,  and  phase  angles  of  y.  The  analysis  may  be  restricted  to  the  lowest  5  frequencies  fi.
Does  Scilab  offer  a  method  for  this?  FFT seems not to be adequate  because  the  signal  is  aperiodic  (silence  after  10  s).
Is  nonlinear  regression  (with whichI'm  fmiliar)  a  promising  way.  The  lowest  frequencies  can  probably  be  concluded  from  a  short  time  DFT  where  damping  is  negligible.
Kind regards
Jens

Would you consider an ARMA model of the signal? You need to chose the order of the system so a bit of experimenting is needed. Just an idea.

ARMA is very much based on stochastics. I don't see this relevant here.

Numerical computing necessarily deals with sampled signals, yielding 
sampled spectra. Now, there is a duality between sampling and 
periodicity: Applying FFT to a sampled signal leads to a spectrum that 
is periodic AND sampled. The fact that the spectrum is sampled means 
that implicitly the signal you have processed has been assumed also 
periodic. This is why boundaries of the sampled signal are of importance 
: If due to a "bad cut" S($) is very different from S(1), then the 
processing will see this cut as a discontinuity, and the FFT will yield 
a non-negligible parasitic power in high frequencies.

On this point of view, your signal is fine : you start at a power 0 
before hitting the gong, and you record the sound down to a very low 
amplitude ~0 => it's OK.

The problem with a simple FFT here is the exp() envelop. The spectrum of 
the "undamped signal" is convolved with the spectrum of exp(), which is 
an exp(). You can write each d_i = D_i*f_i  where D_i has no dimension.
Analysing this kind of signal has led sismologists to invent wavelet 
analysis :)

If you don't want to use wavelet analysis instead, yes, you may try with 
a non-linear regression, with 4*N parameters where N is the number of 
frequencies you wish.
You will likely need a first guess:

  * for d_i: just get the envelop of the total acoustic power fitted
    with a single exp(-D*t), and set d_i_0 = D
  * for f_i, alpha_i, A_i: get the FFT of your signal / exp(-D*t), and
    get f_i_0, alpha_i_0 and A_i_0 from the most powerful harmonics.

Hope this help
Samuel

Hey Jens:

I'm not sure that a gong or a bell that's not "tuneful" (e.g. a cowbell,
as opposed to a church bell) would have components that are well-enough
separated to be easily picked out by any numerical analysis -- but I'm
ready to be proven wrong.  Certainly it should be possible to pick out
the components of a bell that might be used for making music.

I would start with an FFT to get rough values for the f_i and alpha_i.
Then I would use those as starting points for nonlinear regression.

Alternately, if the components are well-enough separated in the FFT of
the captured audio you could identify each component, then for each
component you could zero out the FFT outside of that component's
contribution (remember to retain both positive and negative frequency
components symmetrically around 0Hz), then do an IFFT to get the
waveform for just that component.  This _might_ recover each individual
component well enough that you can eyeball it for A_i and d_i -- at
which point you could either call it good enough, or you could make an
even better starting point for your regression analysis.

hi Jasper,

Yes, we made a decision - and in fact we implemented it already: and we changed it to be simply always use the same thread. That should work for you, right ?

Regarding your other question (api scilab): I believe that there is string support for cpp (we implemented it), however this is still in development, and may still change before the release...

I am pleased with this interface, it is a lot nicer than intersci. The C++ interface is nicer than the C interface, I think, but does not seem to have support for strings and some other data types (unless I missed something). So I am now mixing my approach: "csci" interfaces for all routines that take string matrices as in- our output, and "cppsci" interfaces for all routines that only deal with numeric matrices. Support for string (and other) data types from the cppsci interface would be welcome in the future.

If not the same thread, any application that depends on apartment threaded COM objects or thread local storage will no longer function as it did in Scilab 5. The solution may be to synchronize such applications over a private thread, but that surely will come at a performance cost.

Whereas previous versions appeared to be single threaded from an external DLL point of view, I see that the DLLmain function gets called by a one thread, whereas interface routines get called from another thread. Worse, looks like each interface routine call is made from a new thread. What is the threading model?? Is there a limited number of threads, or are threads created on the fly?

I will give feedback when there is something to say.

Hello Pablo,

Your 'scs_m' variable is a complete diagram created using
`scicos_diagram` `scicos_block` and `scicos_link`. To check that is is
correct, "xcos(scs_m)" will open the graphical editor for the scs_m
diagram.

The documentation is included within the Scilab help.

Hi Fran?ois,

Perfect - yes that would work great for me. Is there an update on the 
alpha available that has this change?

Strings: nice. I am impressed with the API interface.

Best wishes,

Jasper.

Dear sir,

Could you please let me know the command to detect white spaces such
as end of line and tab characters in SCILAB. I tried the "\n" and "\t"
respectively but they did not work.

Thank you very much.

God bless you.

Hello,

If you are processing strings with only ASCII characters -- with no 
UTF-8 extensions --, you may use ascii() and then test the presence of 
ascii(10) for "\n" or ascii(9) for "\t".
But the most efficient way is to use a regular expression. In a regexp, 
EndOfLine is represented with $. As far as i know, it represents  either 
"\n" or "\r" or both. tab is "\t", or any white separator is "\s" (for " 
","\t", "\n" or "\r").

May you post your test with "\n" or "\t", with the way you get/generate 
the string in which you want to detect white spaces? It would help 
answering to you for your application.
Regards
Samuel Gougeon

Thank you very much. The string was generated from Excel 2003 files.
Some cells contained blank spaces which when processed for use in a
LaTeX document or csv file, the blank lines cause errors and had to be
removed manually.

I tried using the expression

    datax = strsubst(datax, "\n", " ");//replace EndOfLine with " " everywhere

to replace the EndOfLine characters with ordinary spaced but this did
not produce the desired results.

You may try

datax = strsubst(datax, ascii(10), " ");
datax = strsubst(datax, ascii(13), " ");

Subject: [Scilab-users] Prompt strange behavior in Windows7/Scilex5
Message-ID: <mt41vf$t6u$1@ger.gmane.org>

Hello.

I'm experimenting with piping commands through Scilex interactive (with 
the goal of interfacing it with an IPython Notebook, actually).

This is one of my problems: the prompt has a strange behavior as soon as 
a command gets a delayed error (e.g., the command opens a window in a 
separate thread; then the windows throws an error). I don't know how to 
restore the normal behavior.

Steps to reproduce (Windows 7, Scilab >= 5.4):

1)launch Scilex (or Scilex -nw)
2)type: clf;
3)A Tk window opens. Fiddle with it to get an error.
(E.g.: trying to change the axes (Edit/Axes properties), you get in the 
console: Error: can't read "wfortree": no such variable)
4)Back to the interactive prompt, press Enter.

At that point, the input isn't functioning correctly anymore.

- two prompts appear in a row instead of one
- the history works correctly
- but any commands you type directly won't be displayed at all (and 
won't be executed except if you press Enter twice, and then strange 
characters are added to your input)

I suppose that all this is already documented, but I can't find anything 
related to the question (I tried many searches in Google/SO/gmane but 
without success).

Could someone, either point me to the right page, or tell me how to 
restore the correct behavior without a reset, or better yet, tell me 
what's happening here?

Note. The behavior is correct under the WScilex console, but I have no 
clue about how to pipe instructions through it / get its output.

Thank you.
L. B.

Hello,
I confirm the behavior that you reported. The graphic windows opened 
with clf is a java one, while the graphical Editor is a Tk one.
I do not clearly catch what you need, either using Scilab in batch mode 
-- with no interaction, just piping instructions with the -e or -f 
launching options (-->help scilab)--, or with interaction?
In batch mode, off-screen graphical drivers may be used (-->help driver).

Thank you for your quick answer!

First, about what I want to achieve : I want to interact with a Scilab 
kernel, to which I want to send instructions and get the output 
(including the error messages I guess) in a consistent way. Meaning that 
I should be able to force the kernel (or in my case, its input loop) to 
be in a state where it's able to interpret my commands, whatever errors 
it got from the preceding ones.

But I need a persistent kernel : I want the variables and functions to 
persist from executing a group of commands onto the next one. So I can't 
just throw up a new one every time.

I managed to do all this, but crudely (btw, the idea is not from me) : 
open a single Scilex process with pipes at both ends, send and read, 
with tweaks:
- send only commands garanteed without errors (the other ones are 
encapsulated in a temporary exec file, with a tweak to grab the ans 
value) because errors change the Scilex input ("prompt") state
- getting Scilab to put some marks in the output to better interpret it.

I was elated when I managed to display a plot this way, then near 
despair when I saw I couldn't interact with it by using the graphical 
interface (the -nw switch doesn't have any visible effect).

Note. I have a similar problem when I use the editvar widget.

Right now, I'm running out of ideas to circumvent that problem, so I'm 
trying to understand what causes it. While investigating, I stumbled on 
the strange behavior I described, and that's why I'm trying to 
understand it, in the hope that it will help me solve my bigger problem.

Cheers,
Laurent

scilab6?does't accept interrupt command.
Is this bug or not providing that command as alpha stage?

I expect to get the value of yy  less than 0.01 which is the most left value
of x.
But actually I get  0.0591.

When I adopt only the first 3 elements of x and y,it works rightly.
I get 0.0100075 of yy2.

Please tell me where I was wrong in the first script.

Subject: [Scilab-users] animation of multiple plots
Message-ID: <55F823D5.20200@cnrs-orleans.fr>

Hi,

I am trying to animate multiple plots. For instance, when modeling the 
motion of a planet
around the sun, I wish to plot, in one window, the planet's position 
and, in another window, the tip of the velocity vector, both plots 
evolving with time.
I can do that in principle with the following algorithm.
     for each time point
         compute x,y,vx,vy
         define he2 handle of the trajectory
         define he6 handle of the velocity curve
         drawlater()
         subplot(1,2,1)
             update trajectory: he2.children(1).data = [x(t(1:i)),y(t(1:i))]
         subplot (1,2,2)
             update velocity: he6.children(1).data = [vx(t(1:i)),vy(t(1:i))]
         drawnow()
         record gif image
         update x,y,vx,vy
     end
Using imageMagick, I then combine all the gif's in an single animation 
file.

This process works on my computer. I can visualize the animation using 
Irfanview,
Chrome or Internet Explorer, but not Firefox which shows only the last 
image.
The situation gets worse when I try to post this animation on the Net: 
no program
that I know of can display the animation, they all display the first image.

I have written other animations which behave properly (see 
https://grenoble-sciences.ujf-grenoble.fr/pap-ebook/grivet/liste-animations). 
However, there is one,
probably significant, difference: these working animations don't use 
multiple windows.

I would be very grateful for any suggestion on how to run two animations 
side by side.
Thank you in advance for your time and help.

Hi,

It does not sound like a Scilab issue, more a problem with ImageMagick/gif.
Anyway, you can send me a couple of gifs (a working one and a 
problematic one) and I'll try to have a look.

Cheers,

Antoine

Subject: [Scilab-users] sometime fail to save a file
Message-ID: <1442331421891-4032831.post@n3.nabble.com>

In below script,,It sometime fail to execute the line 'save(fileName,y)' 
with the error message 'save can not open fileName' where fileName is the
specific name depending i.

But after stop, I can execute that line by selecting it and executing with
echo  .
The value of i which makes error changes.
So I can't run whole process.
Is there any advise to fix this problem

Best regards.

Strange. It does not seem to be a Scilab problem, Each gif image is a
bitmap so  there is no reason why several sub windows create a problem....

I cannot remember the name of the application, but there is software out
there that will take a number of static images and compile them into
mpeg or other "movie" format.

I've done it, but it was long ago on a computer far, far away.  I'd have
to google for it, and my Google Fu is not something to write home about
-- try some variation on "animated movie from stills" or "jpeg to mpeg"
or some such.

I personally use The Gimp to generate animated GIFs, and it usually works fine.

You're welcome.
I hope you've been able to figure out the typo in line 51.
Moreover, as you might have already figured out, the for-loop can been
replaced by using the .*. operator.

Except the fact that you wrote stri*m*g instead of sting, I got no problem with your script on my side (used x.^2 for f).

Hi,
Many thanks to all who responded to my post. Your help is all the more 
commendable that my
problem had (as Serge pointed out) nothing to do with Scilab.

Special thanks to Antoine Monmayrant who discovered my error. When 
creating an animation with ImageMagick,
one may specify a parameter (-delay) which is the delay between 
successive frames. I sometimes chose (randomly) a zero value. With 
recent versions of Firefox, this is equivalent to showing the last 
frame. Any non-zero value leads to a correct display. Such is not the 
case with Internet Explorer which apparently forces a minimum value of 
this parameter.

Subsidiary question to Antoine. I know how to set the delay (-delay nn 
or -set delay nn), but how can I find out its value for an existing 
animatio ?

Cheers,
JP Grivet

Each frame can optionally have its own delay, you can see this
in the layer names if you load it in GIMP.
I don't know how to do it in ImageMagick though

C'est loin d'?tre optimum, mais en ouvrant l'animation gif dans Gimp, 
les diff?rentes trames apparaissent comme des calques (Ctrl+L pour les 
voir) avec le d?lai d'affichage de chaque trame indiqu? ? c?t? du calque.
Il doit y avoir des outils plus adapt?s ( http://www.lcdf.org/gifsicle/ ?).

Here is how to do it with ImageMagick (from the page 
http://www.imagemagick.org/Usage/anim_basics/#study,
which I should have read long ago). This command line statement (under Win7)

             identify -format "  %T" myfile.gif

will print the delay (in hundredths of seconds) between each frame of 
myfile.gif.
Simple !
Cheers,
JP Grivet

Hello,

I am sure there is no error in the script because selecting that line to
execute works with no error just after error happened in the run of whole
script.
Actually I load a same file, renew value of y and before save the file.
So the error  might be due to loading and saving a same file in very short
time.
I don't know the internal structure of scilab.
If some one can think possible cause of the error, please suggest some
solution.

Best regards.

The small script you sent did not reproduce the error.
Maybe you could try to create a minimal script that generate the error, and share it with us.

Message-ID: <1442492140766-4032849.post@n3.nabble.com>

Hello to all,
I am new in this forum and I use sometimes scicos.

Now I'd like to create a script which creates a custom block in Scicos. The
structural information are read from an excel file. In the m-language there
are two commands new_system(...) and add_block(...) in order to perform this
task and there are also commands to create ports, links between the blocks
etc.... Which are the corresponding commands for Scilab?

Here is my m-code:

***************************************

[num, txt] = xlsread('TCS.xls');
dim = size(txt);
laenge = dim(1,1);
breite = dim (1,2);

PathFlag = '<<Path>>'; 
InPortFlag = '<<In>>';
OutPortFlag = '<<Out>>';

Hello Yves and welcome,

Yep, it is possible to instantiate a diagram using the functions :

 * scicos_diagram()
 * scicos_block()
 * scicos_link()

to add a block simply append the block (here named `blkX`) to the list
of children of a diagram (here named `scs_m`):

```
scs_m = scicos_diagram();
blk1 = scicos_block();
// or instantiate a block
blk2 = BIGSOM_f("define");

scs_m.objs($+1) = blk1;
scs_m.objs($+1) = blk2;
```

Everything is documented on scilab help pages and to check do not
hesitate to use `xcos(scs_m)` to watch the resulting diagram. You can
also draw a template diagram on xcos and then export it to Scilab
(using the diagram browser).

Regards,

Hello Cl?ment,
I have tried it. But it is really not obvious to me how to use e.g
"scicos_block" (graphics, model, etc...). Even the help didn't give me
further information. Even by looking at the .sci file I couldn't get it. 

Is there some example code how to create a custom block with inputs,
outputs, connections?


Thank you

Yves

If you access a file that rapidly, all kinds of things may have a lock 
on it. Try disabling your virus scanner for a few minutes and try again?

Best wishes,

Jasper.

Dear user group,

I need to extract the Jacobian from the lsqrsolve function. The fortran
routine lmdif (http://www.netlib.org/minpack/lmdif.f) provide this as the
output fjac, but lsqrsolve does not have this option.

I need to evaluate the goodness of a regression I made using lsqrsolve and
I found that this is done through the correlation matrix. I need either the
correlation matrix or the jacobian.

I would like to get an output similar to the following

Final set of parameters Asymptotic Standard Error
======================= ==========================
m = 0.174844            +/- 0.0002964 (0.1695%)
b = 1506.34             +/- 5.756 (0.3821%)

correlation matrix of the fit parameters:
       m     b
m  1.000
b -0.448 1.000

Regards

Pablo

As suggested by Jasper, you should not access the same file that fast 
without a bit of caution.
Can you try the following script:

for i=1 :100
    y=i^3
    save('test_'+string(i)+'.dat','y');//new name for each file to avoid 
accessing the same file over and over
end

?

Do you still have your problem with this script?

Antoine

Hello,

You can use the numderivative macro, with your residual function as 
first argument.

Are you wondering about save() returning without waiting for the file

or with sleep(100); for instance?

Hello,all

Both solutions are fine!!

The reason why I want to save every time, I want to keep the result.
Renewal of y's value depends on the other condition and when renewal process
is skipped the same file is accessed rapidly.
(Actually this phenomena began to happen after I replace my old PC with more
fast and multi-core PC)  
Any way I understand the cause of the error, so I modify the script into
saving once in 10 renewal or sleep(100) whenever renewal is skipped.

Best regards.

Hii everyone,

Could anyone figure out the issue I had posted. What I could find out is
that the Error message that I am getting is Numbered as Error 117 in the
error table of Scialb Help. This problem is still unresolved. Kindly help
me out. I have already attached the .xcos file in which I am having
trouble. Any kind of solution if anyone comes across please let me know.

Hello Cl?ment,
it works. I don't know why but yesterday I didn't see the small square (the
system) that has been created in the Scicos model. 

Thank you

hi St?phane,

We've (somewhat) fixed the website; the page http://www.scilab.org/development/nightly_builds/master now has the latest builds listed. Some are a few days old, and there are still other issues (the commit date seem to be wrong, as well as the size) -- but at least they are recent builds. It'll most likely continue to be this way... not perfect, but at least available...

Hello Cl?ment,
it's really not so easy to begin with writing sce scripts.

So I could finally after hours of research and trials partly understand how
this scripting works.

Here is my code:

**********************
scs_m = scicos_diagram();
scs_m.props.title = "Test_Superblock";

//SUM-Block
//scs_m.objs(1) = SUMMATION("define");
//scs_m.objs(1).graphics.sz = [30 50];


//super block
scs_m.objs(1) = SUPER_f("define");
scs_m.objs(1).graphics.sz = [200 200];

//create one additional input
scs_m.objs(1).model.rpar.objs(3)= IN_f("define")

//define input-structure
scs_m.objs(1).model.in = [2;-1]
scs_m.objs(1).model.in2 = [1;-2]
scs_m.objs(1).model.intyp = [2;-1]



xcos(scs_m)

**********************

I have some questions:
- what are the vectors in[2; -1] and in2[1; -2] ? I write it just
"instinctively" by looking at the diagram browser.
- is there not another simplier way to create inputs in a kind of one
command like "create_input"?
- is my code correct or did I forget something?

By the way I don't know how to export a model to the "diagram browser". When
I open it I see a tree structure. From there I deduced how to create
sub-model-elements. But I don't know if my code is complete or if there are
some additional things necessary.

If I could get some example code from somewhere it would help me a lot.


Thank you



Yves

Hello Yves, hello all,

Yep in fact this is not trivial and we try to improve that for Scilab6
(such as automatic definitions of port properties).

> I have some questions:> - what are the vectors in[2; -1] and in2[1;

Your code seems correct. The model.in and model.in2 let the user
specify the size of the inputs.

Opening the diagram browser push an 'scs_m' variable into Scilab and
you can then access its fields.

thank you! I solved the problem with your hint. For further reference I
attach a ZIP file with a linear regression comparing statistical results
from Scilab and gnuplot.

It is called a /structure/, and keys are fields.
aa("key1") = %pi
aa("boo") = %t
aa("pol") = (1-%s)^3
aa("txt") = "Hi"

Hello Samuel

Thnks a lot.

This is  exactry what I want.

Is there any function f(a,b) which return ka where
[x,ka,kb]=intersect(a,b).
I want to get only ka.

It's not possible. The first argout can't be skipped, just ignored:
[trash, ka] = intersect(a,b)

Subject: [Scilab-users] Cannot understand scilex behavior when piping
In-Reply-To: <mt4abv$qh8$1@ger.gmane.org>

Hello.

I'm still trying to pipe instructions into scilex (Windows 7, Scilab 5.4).

When I send a plot command, scilex opens the graphics window and draw my 
polyline -> Great !

Then I try to open the graphics editor from within the graphics window 
(e.g. Edit/Axes properties) : nothing happens.

Then I close the graphics window.

Then I send the plot command again. And poof! The graphics windows opens 
AND the long awaited graphics editor too. Except that nothing works in it.

I guess it's some sort of handlers problem: the graphics window cannot 
communicate correctly with the scilab kernel and get the correct 
handlers to the figure.

What's more strange, is that the behaviour is correct when I start 
scilex from within an interactive console (cmd)...

Steps to reproduce (you need some utility like cat from gnuwin32, or any 
way to pipe commands to scilex) :

(Incorrect behaviour, with a pipe)
<from an interactive cmd.exe>
cat | scilex
x = 0:0.1:10
plot(x,cos(x))
<the graphic window opens>
<click on Edit/Axes properties>
<nothing happens>
<close the graphic window>
plot(x,cos(x))
<the graphic window opens, and the graphic editor too (but it isn't 
functional)>

(Correct behaviour, without pipe)
<from an interactive cmd.exe>
scilex
x = 0:0.1:10
plot(x,cos(x))
<the graphic window opens>
<click on Edit/Axes properties>
<the graphic editor shows up immediately and is functional>

I don't understand how scilex can see any difference between both 
approaches, and why it would have a different behaviour based on that 
difference. From its point of view, there shouldn't be any difference.

Ah! And the -nw switch doesn't change anything... You get exactly the 
same behaviour in both cases.

Can someone give me some sort of solution, or pointers, or even give me 
an idea for a workaround. I need to pipe things in scilex, and I need 
the first approach to work correctly...

Thank you.
Laurent

I see there are Java and C interfaces, has anyone tried to call ones of the base functions (log, exp, ...) to see how ti compares to scilab builtin's?

Hi:? I'm using plot() and find that if the caption is too long, then part of it can't be seen. If I resize the figure and turn off auto_resize, then part of the captions is still not drawn. But if I turn on auto_resize, then the figure enlarges, and the captions is still too long. What should I do??????????????? Da Feng

shorten the caption, as using a reference as caption and give its full 
text elsewhere, or reduce its font size.

For a certain plot, there will always be a length for its caption that 
will require more space than the plot itself. So, you have to chose what 
should take most place: the plot or its caption.
This is why one couldn't advice you to decrease the margins sizes.

If I'm writing a paper then I generally put very terse captions or (more
usually) no captions on the plots, then use whatever editor I'm using
(usually Lyx/LaTeX these days) to caption the plot "properly".

However, sometimes I need to email just a plot to someone -- to convey
"see it works!" or "this is how disaster is striking".

Is there a way to put a linefeed into a caption for those times, or a
block of text?

Message-ID: <448049475.783778.1442822433086.JavaMail.yahoo@mail.yahoo.com>

Hi,
I need to model the current in a solenoid. ?I would use a resistor with the standard inductor model but the inductance changes considerably with position of the solenoid plunger (as the solenoid is closing). ?The standard inductor model only accommodates a fixed inductance.
The equation for inductor current is:
? ? ? I(t) = (V/R)[1-e?(-Rt/L)]
Anyone have any suggestions?
Thanks,

Hi:?? I find a solution. I use larger y axis of data_bounds to press down the curves, and then increase y axis of? the figure_size. The results is acceptable. Actually I've drawn 8 curves and their shape is not ideal for placing the captions.???????? Da Feng

Hi:?? I find a solution. I use larger y axis of data_bounds to press down the curves, and then increase y axis of? the figure_size. The results is acceptable. Actually I've drawn 8 curves and their shape is not ideal for placing the captions.???????? Da Feng

 If I'm writing a paper then I generally put very terse captions or (more
usually) no captions on the plots, then use whatever editor I'm using
(usually Lyx/LaTeX these days) to caption the plot "properly".

However, sometimes I need to email just a plot to someone -- to convey
"see it works!" or "this is how disaster is striking".

Is there a way to put a linefeed into a caption for those times, or a
block of text?

Hey Mike:

That's the equation for inductor current when driven by a voltage, yes.
It comes from the differential equation:

i(t) * R + (d/dt i(t)) L = V.  It's a first-order ordinary linear
differential equation.

Life gets complicated when you have that solenoid in there.  I'm almost
certain that the correct way to model the i/v behavior of the solenoid
is

v_l(t) = d/dt (i(t) * L(t))

-- in other words, accept that both current and inductance change with
time, and take the derivative of the pair.  The place to look to check
up on my assumption is texts in electrical machines (it's a 3rd-year
electronics course.  My book is "Electric Machines: Steady-State Theory
and Dynamic Performance" by Mulukutla S. Sarma, WCB, 1985.

Note that, at best, you'll have to treat the system as a time-varying
linear system, and you may have to treat the system as being nonlinear
(depending on how quickly the solenoid position varies with time
compared to the current).  You'll also see that finding the inductance
vs. position relationship is (ehem) left as an exercise to the reader.

This isn't a complete answer, but I hope that it sets your feet on the
right road.

Hi Tim,
Thank you for the quick feedback. ?The inductance changes with position and I have taken measurements of the inductance vs. position. ?I have the position data from model of the mechanical system, a simply sprung-damped mass system. ?
What I don't know how to do is to either break up the math into constituent blocks (I can't find a block for Euler number or to program a block that can take the inductance in as an input parameter (although I do program in various languages, I've never programmed in scilab or xcos before). ?
What would be the best way to proceed, in your opinion? Separate blocks or program a custom block?
Thanks,
Mike

Thers is no stair function but you can obtain this king of plot using
the polyline_properties:

clf;plot(sin(linspace(0,2*%pi,40)))
e=gce();//plot creates an entity of type compound
p=e.children;//the handle on the polyline
p.polyline_style=2; //set stair case mode

	vector
Message-ID: <1443351217820-4032900.post@n3.nabble.com>

Hi all,

I was wondering what are the possibilities to do a product element by
element between a matrix A (m rows ,n columns)and a vector (let say column
vector v (m elements) ): I want each element of each column of A to be
multiplied by each element of v at the same row. What I'm using for now is a
product by a diagonal matrix based on v. For large matrix in data
manipulation (typ. 100000 rows), it's necessary to use sparse to allocate
better the diag matrix otherwise it's out of memory for usual machine.
So i'm using --> diag(sparse(v)) * A

Have you best practise to share on this topic ?

Thank you all,

David

I am not sure to catch what you want to do, noticeably what is the 
format of the result you expect.
AFAIU, i would do
A .* (v*ones(1,size(A,2)))

.
The sparse encoding may become bulkier than the dense one if the actual 
density of contents is not low.
Now, are A or/and v actually sparse (i mean with a low density)? You did 
not give infos about that.

"Otherwise it's out of memory for usual machine"

Meaning, he tried that, and it didn't work.  So he does what DOES work,
which is

diag(sparse(v)) * A

This makes the matrix on the left sparse, with a populated diagonal and
all the rest zeros (presumably v is fully populated).  And, as David has
discovered experimentally, it does not run him out of stack space.

You may already be using the best way.  Something to try would be

B = A;

for n = 1:size(B, 1)
  B(n, :) = v(n) * A(n, :);
end

I suspect it'll be slower, but you can always give it a whirl and see.
Use tic() and toc() for timing.

If you want to engage in heroic measures, write a C or FORTRAN function
to do what you want, and then learn how to dynamically link it to
Scilab.  I've done this in the past for quaternion arithmetic in a
Kalman filter, but it was a lot of work and not 100% robust in the face
of Scilab upgrades.

Also, if you don't already know about it, stacksize is a handy Scilab
function if you're working with large data arrays.  "stacksize max" will
either give you the biggest Scilab stack that can be had or crash your
machine, depending on your version (it appears to work in the current
version).  "stacksize(nnn)" will set your stacksize to nnn, without
crashing your machine (to my knowledge).  "stacksize" will report the
current stacksize.

Subject: [Scilab-users] multiple element by element between large matrix

Hi ,

Indeed it's the way I found to get it work on my machine.
Each element (double) of v is distinct of each other, it's a kind of sizing factor that I want to apply on all the columns of matrix A (double), according to index of the row.
Usually for such element by element I would have done:

B=A;
For k=1:size(v,1)
	B(:,k)=A(:,k) .* v
end
 but it's a loop that I want to remove on speeding-up purpose therefore I tried the proposed workaround.
 Thank you for your feedback.

David

You may already be using the best way.  Something to try would be

B = A;

for n = 1:size(B, 1)
  B(n, :) = v(n) * A(n, :);
end

I suspect it'll be slower, but you can always give it a whirl and see.
Use tic() and toc() for timing.

If you want to engage in heroic measures, write a C or FORTRAN function to do what you want, and then learn how to dynamically link it to Scilab.  I've done this in the past for quaternion arithmetic in a Kalman filter, but it was a lot of work and not 100% robust in the face of Scilab upgrades.

Also, if you don't already know about it, stacksize is a handy Scilab function if you're working with large data arrays.  "stacksize max" will either give you the biggest Scilab stack that can be had or crash your machine, depending on your version (it appears to work in the current version).  "stacksize(nnn)" will set your stacksize to nnn, without crashing your machine (to my knowledge).  "stacksize" will report the current stacksize.

As a reference, David posted a bug on that 
http://bugzilla.scilab.org/show_bug.cgi?id=14176?and he targets Scilab
6.

So I have a question on your needs for Scilab 6. There is currently no
more stacksize as all the system's memory is available. To protect
users, I suggested to re-introduce `stacksize` with a changed behavior
:

 * M=stacksize(N) : will set N * sizeof(double) bytes available on the
Scilab datatypes raw memory
                    will return M the previous sett'ed value
 * stacksize('max') : will disable any memory restriction

## Why re-introducing `stacksize` ?

On my Linux system (with 8Go of RAM and some applications started),
allocating all my memory (like with `zeros(2**30,2**3)`) slow my
computer down and succeed after a lot of time. Reducing the memory
available to Scilab using `stacksize` will help user discover algorithm
or memory issues more rapidly and without swapping most of the other
applications *by default* .

My point is not to limit the available memory issue but ease language
usage for new-comers by protect them against typo or mis-design
algorithms.

Awaiting your opinion,

I second this proposal, I think it's not a good thing for scilab to 
allow "by default" to bring someone's computer to a crawl.
It's a good way to turn users away.
For me, this proposal fits in the same category of improvements than any 
solution to the forgotten ";" of death (if M is a huge matrix and you 
type "M" instead of "M;", you are greeted with an endless printing of 
numbers that you cannot interrupt, even with Ctrl+C).
Can't we at least get a warning when we tend to consume way too much 
memory (ie above a certain % of the total available memory)?

Cheers,

Antoine

I agree with the proposal to reintroduce stacksize for the reasons explained.
As Antoine suggests, It would make sense to have a safe "default" value for the  "default" max allocable memory, related to % of installed hardware memory (2, 4, 8.. Go) and appropriate warnings when you go above. Then user could set by himself a desired max allocable memory value and in this case, if you try  to allocate more, Scilab issues an error of max memory reached.
I think this could satisfy each user: for the first works on new data, you might be happy to have the max possible memory to run first your script and see the first results (default on stacksize), eventually being aware of risk of memory issue (warnings), then you could improve robustness of your script by tuning code and sizing the memory as further steps.
Thanks,

David Ch?ze

Should this be turned into a bug report or a SEP?
What would make more sense?
Out of topic, but what about the missing ";" of death ?
I quite like what Julia is doing by omitting the central part of arrays, 
only showing the head and tail:

What do you think?

Well, this started as a bug report but closed as worksforme as it works
on my machine. For me this behavior change should not be on a SEP as we
are on a major release but should be clearly state in the documentation
(history part).

>From the user perspective, the common `stacksize("max")` does not have
a modified meaning but behaves differently. In my view, this re
-introduction is kind of an "implementation detail" ; the only strong
point is that Scilab 6 has been presented as a Scilab without stack
limitation (and thus without `stacksize`).

Seems linked to the `lines` function. Would you open another ML thread
on that topic please ?

Hello,

To handle a cross-platform sound handling in Scilab I suggest you to
take a look at JIMS and the "Java Sound API". Not sure if it will fit
your needs but might be.

Note: another more advanced approach is to use SWIG-Scilab to generate
the mapping of a library (Gstreamer might be a good cross platform
candidate).

If your points are given by cartesian coordinates stored in 2 arrays  p1
and p2
you can compute the distance between these 2 points with
norm(p2-p1)
or equivalently by
sqrt(sum(p2-p1).^2)

I think you are missing brackets there, presuming .^ now operates on the 
sum?

Hi Peter Q

This question is just the strangest question I have ever seen on the 
Scilab forum. I'm not sure whether I shall think this is spam? ... 
alternatively, consider reading a Calculus book from high school. 
Possibly come back with a more well-defined question.

Best regards,
Claus

Sharing the thoughtful skepticism of Claus, i would say: If the points 
are lying on a sphere and you are looking for the shortest direct arc 
linking them along the sphere, the Wikipedia page about spherical 
trigonometry might help you: 
https://en.wikipedia.org/wiki/Spherical_trigonometry
Then, the usual cos(), and sin() Scilab functions will allow you 
implementing the relevant spherical formula.

Hello,

In the help, it is specified that the syntax 'for e = l ...' when l is a 
list is authorised. When l is replaced by a vector, the result appears 
to depend on whether its a column or row vector :

With this code, the for loops runs 3 times and each time i is equal to 
another value of the vector idx

idx =[1 2 3];
for i = idx
     disp("newIter")
     disp(i)
end

When the vector idx is a column vector now, there is only one loop and i 
is equal to the vector idx

idx = [1 2 3]';
for i = idx
     disp("newIter")
     disp(i)
end

Is this behaviour intended?

Yes, and it is as well documented:
-->help for
"Description: .../... If expression is a matrix or a row vector, 
variable takes as values the values of each column of the matrix."

You're welcome.

I personally think that we should sometimes simply answer elementary questions without sarcasm, as it is good news: the popularity of Scilab increases and people start using it without being senior calculators (this is also for myself, as I confess I have been myself sometimes sarcastic).

If we suspect some lazy student, maybe we could discuss to have a common and adapted answer, such as asking first for the formulas before helping coding it.

Regards

Hint: you can transform any matrix A into a line vector using
A(:)'

So in the present case, try the following code and see the difference

idx = [1 2 3]';
for i = idx(:)'
     disp("newIter")
     disp(i)
end

Hope this helps

Since the 6.0.0-a1 release, several bugs somewhat linked to memory 
saturation were reported.
After one of them, you are going to allow users to configure the maximal 
recursivity depth.
It will be a useful improvement to avoid memory overflow, but it is not 
sufficient to avoid
saturations. Indeed, not only the number of recursive calls is involved, 
but also the
quantity of additional intermediate memory used by each call, which 
usually depends on
the recursive level reached, etc.
The fact that memory management is changed in Scilab 6 does not kill the 
need to control
the maximal amount of memory to ascribe to each Scilab session, because, 
unfortunately,
operating systems do not always manage the computer ressources in 
processors and
RAM load or interruptions in a relevant or efficient way to avoid 
"burning" a processor.
IMO, this is not a matter of Scilab 5=>6 back compatibility. It is a 
main specific characteristic
of major releases to not be necessarily back-compatible with the 
previous ones.
So, which function with which features ?

* setmemory() would be a better name than stacksize():
    It is converse to getmemory(). It is more explicit and user-oriented.

* it should merge in a whole local intermediate and global memory 
domains, corresponding to
    the former stacksize() and gstacksize().
    This is another reason to not use "stacksize" as function name.

* It should work in Bytes, not in doubles.
    The documentation has always been somewhat confused about unit used 
for amounts of memory,
    mixing "double" with "word" (a word = 8 bytes. not really common for 
users).
    The standard unit is either the bit or the byte. There is no reason 
to stress on the 8-bytes "double".
    Scilab deals with int8, int16, int32, int64, double. By the way, 
"double" is an oldies.
    Amounts of RAM, disk spaces, etc are given in bytes, not in doubles.
    So, let's make setmemory() working in bytes.

* The last question i have in mind is about the Java memory heap that 
can already be configured
    through preferences, and reserved to Scilab usages.
    a) it should be decided whether the memory amount set with 
setmemory() should take the Java
         heap into account or not. IMO, it should include it. Or an 
option should specify it.

    b) Is the amount set for the  java heap reserved for the only Scilab 
session, or is it shared for
         all running scilab sessions? It may be an obvious question for 
a developer, but it is not
         clear for me. It would deserve to be documented.

    c) i think that setmemory() should propose an option to set the java 
heap amount, as a
        shortcut to the preferences, in such a way to be a "single desk" 
for all memory settings
        for scilab.

To be discussed.
Anyway, thanks for your proposal, since yes, a memory setting function 
is still needed.

Best regards
Samuel Gougeon

Hello,

You cannot protect users from OS memory allocation errors. There can be 
other softwares running on the machine that consume a big amount of 
memory, like VirtualBox. You can have also low end machines with a low 
RAM size.

The only way is to a implement a dedicated memory manager which 
allocates a big memory buffer at startup, and manages all the memory 
allocations in it....exactly what Scilab 5 does.
There are some uses cases for which this system can be useful however, 
but not to prevent coding errors.

By the way, the goal of tuning the Java heap size is to optimize the 
time production servers spend doing garbage collection. I don't think we 
have this problem in Scilab.

Simon

So, my questions are:
* can't the same be implemented in Scilab 6?
* If yes: is there a way to implement it in such a way that sharing 
between global and local+intermediate variables/memory would be set 
dynamically, in a transparent way for the user that would not have to 
specify fixed amounts for each kind of variables?
* How the "default" buffer is initially sized in Scilab 5? Does it take 
into account the available memory at the time of launching the Scilab 
session, such as it could be different from a Scilab session to the 
other, particularly when several concurrent Scilab sessions are 
simultaneously run on the same computer? How could it be managed in 
Scilab 6,  while the former Scilab memory limit that became quite 
smaller than common available RAM does no longer hold?

Which problem are you referring to?
Knowing almost nothing about JVM and memory management by Java, i am 
rather unable to understand the meaning of your answer wrt my initial 
question about tuning the size of the java heap from Scilab. In a 
practical way, what can be noticed is that when using a lot of graphics 
in Scilab -- like for image processing --, some java exceptions can be 
avoided by increasing the size of the java heap. For practical usage, my 
remaining questions are:
* Is this setting a memory reservation?.. in such a way that increasing 
the java heap max size makes this memory unavailable for other processes 
external to Scilab, or even unavailable for other Scilab sessions 
running on the same computer?
* Does each Scilab session have its own java heap, or is the java heap 
shared? In the first case, including its setting through setmemory() of 
a session could be meaningful.

The meaning of my first post was that, from a user point of view, 
knowing that the amount of memory involved in a Scilab session is of 
"Scilab global kind" or of "Scilab intermediate kind" or of "java kind"  
or of "TCL kind" (for so-called TCL interpreters) is of no importance. 
The only thing that really matters is that my calculations and graphics 
work within a specified total amount of memory. In an ideal world, even 
the size of the java heap should be dynamically set as a part of the 
total amount of memory set for the Scilab session. It might not be 
possible, but it was the idea of my question/discussion.

Samuel

PS: By the way, in Scilab 5, are the TCL variables -- that are 
"persistent" -- stored in the global area, or anywhere else?

Hi Christophe, et al.

Sarcasm can create an unpleasant atmosphere, which is generally not 
desirable in a forum. Just ot be clear, I don't see any sarcasm in my 
own response. If you see it otherwise, please explain.

When it comes to my points, please bear in mind that I did find the 
question by Peter Q highly suspicious. I think that very simple 
questions needs to be turned over and studied further. Also please be 
aware that if young people show up and need answers, it could interfere 
with educational programs. Therefore skepticism may be just right under 
certain circumstances.

An approach for helpers in the forum could be, that if a question is 
very simple, consider asking questions, like for example "what is the 
general purpose?" - and/or - "can you explain more about the problem 
you're trying to solve?"

I appreciate Samuels reply in that the answer may not be so simple, if 
the space is not a simple cartesian space. This was also part of the 
thoughts underlying my response. I was thinking, "where's the catch?"

I do think that the forum members should be concerned with interfering 
with educational programs (like classes in school).

Best regards,
Claus
