Hey,
is it possible to have this
msprintf('%.f kWh',2725977)
output something like "2.725.977 kWh" or even better "2?725?977 kWh" (with

Thanks

Hello,
I would recommend changing to SCILAB 6. There the stacksize doesn't exist and you can use the installed memory of your PC.

Subject: [Scilab-users] Increase memory

Hello

I'm working with very large matrices and I use the karmarkar function.

When processing comes to the karmakar function.
Scilab says:
"Stack size has been exceeded!"

I used the maximum stacksize value but the error remains.

My running computer on Windows has 8GB of memory so that the computer is not the limiting factor. There is a way to increase the maximum stack size?

Message-ID: <CAHbxmFSi5A7FA2hCuOxnUpfBUOxzZ=gY7sgsg6f89BGZ2_8pBA@mail.gmail.com>

Hello,

I'm building a toolbox where I have to link a static library (.a file).

I'm able to build the toolbox using *exec builder.sce*.

I have the following line in the .start file

*link(lib_path + "/liboctave.a");*

When I load the toolbox using *exec loader.sce*, I get the error

*link: The shared archive was not loaded: liboctave.a: invalid ELF header*

If I change it to* link(lib_path + "/liboctave");*, I get the error *:
cannot open shared object file: No such file or directory*

How do I use link() to link a static library in the .start file?

Regards,
Shamika

Hi,

The thousands separator flag for the printf (apostrophe) is non-standard and it does not seem to work in Scilab.
You may need to program this in order to get a nicer printout.

Rafael

Hi Richard,

Are you sure that a relative accuracy of 5e-8 of your result is relevant/actual/significant?!
(.f displays 6 decimal digits after the dot).
If yes, and if 
msprintf('%5.2f GWh',2725977/1e6)
does not match your actual data and relative accuracy, AFAIK there is no way with the Scilab C format to group digits.

So, you may post-process the resulting string with some strsplit(s,..) and strcat(s, " ") calls.
Tuning the space's width is mainly/only possible with a LaTeX rendering on graphics.

HTH
Samuel

Hi,

I have a problem loading the SIVP toolbox 0.5.3.2 from the ATOMS module manager under Linux Mint 18.1.

I get error: The shared archive was not loaded: libtiff.so.4: cannot open shared object file: No such file or directory (see attachment).
I read somewhere it has also been known on Ubuntu distro and was something to do with a labeling issue with *.so.* files.

Is there a workaround? If you could tell me what to type i'll have a go.

Thanks, Dave

Hello, 
I have a similar problem as your problem no.4, some of my Xcos 6.0.0 block
diagram files can be edited, and saved, and simulations can be run without
problems, but next time Xcos is opened the block diagram has disappeared.
The file size is not zero, so it seems like the file has some data. I have
only tested it on Windows 10.
Any ideas how to solve this problem?

Hello all,

Since Tuesday evening, services around xxx.scilab.org are interrupted by 
a hardware failure of an internal connection.
ISP is working on it.
In the meantime, ITs start to move servers ( VM ) to another site.
They started by the mailing list server.

I do not have more information except that it is not voluntary.
And that ESI IT teams work to solve the problem.

Regards,
Antoine

first try to locate the lib on your system :

sudo find /usr/lib/ -name "libtiff.so.4*"

/usr/lib/x86_64-linux-gnu/libtiff.so.4.3.6
/usr/lib/x86_64-linux-gnu/libtiff.so.4

if the "libtiff.so.4" doesn't appear  add a symbolic link to the
existing one in the same directory :

cd /usr/lib/x86_64-linux-gnu/
sudo ln -s libtiff.so.4.3.6 libtiff.so.4

Message-ID: <1510065525808-0.post@n3.nabble.com>

Hello,
I have logfiles in the following form:
DESC: AAA 2017
Datum;Zeit;kWh
01.01.2017;06:00;419,942
01.01.2017;07:00;513,273

01.01.2017;10:00;606,592
01.01.2017;11:00;594,92
01.01.2017;12:00;594,92
01.01.2017;13:00;524,933
...

I can read these in either as double or string
[log_data, comments] = csvRead(log_file, ";", ",", "double",[],
"/^[^0-9\-]/");

[log_data, comments] = csvRead(log_file, ";", ",", "string",[],
"/^[^0-9\-]/");

However what I'm missing is a way to convert the date & time column to a
date format in scilab. There doesn't seem to be function for this in scilab.
Is there a recommended way of doing so?

Thanks & regards
richard


PS:
I'm so glad the list is working again! Would have been nice tho to inform
the users in advance and with some sort of status.scilab.org site or

Hello Richard,

There are:

datevec
datenum
getdate

that could do the job.
I am not sure whether there is a recommended way of doing the conversion.

Assuming you have two header lines in your files, try this:

tt=csvRead(log_file,";",[],"double",[".",";";":",";";",",";"],[],[],2)

tv=datenum(tt(:,3),tt(:,2),tt(:,1),tt(:,4),tt(:,5),0)

use datenum and datevec , example :

yourline=["01.01.2017"; "06:00";"419,942"]
// D=day, M=month,Y=year
DMY=tokens(yourline(1),".")
execstr(strsplit("DMY","")+"="+DMY)
DT=datenum(y,m,d)
[Ye,Mo,Da,ho,mi,se]=datevec(DT)
// h=hhours, m=minutes, s=secondes
hm=tokens(yourline(2),":")
execstr(strsplit("hM","")+"="+hM)
s=27
DT=datenum(y,m,d,h,M,s)
[Ye,Mo,Da,ho,mi,se]=datevec(DT)

Thanks for getting back Philippe.

Only so.4 appeared. Checking with Nemo I have:

libtiff.so.4
libtiff.so.5
libtiff.so.5.2.4

All have identical size and time stamps.
Nemo reports 'link to unknown' for so.4 and so.5, and 'unknown' for so.5.2.4

Could you please advise on terminal commands to set up symbolic links to 
correct files?

Regards, Dave

Hello,
thanks for all the replies! Somehow datenum and datevec slipped thorugh my
search ... :-/

Jan's approach seems the most suitable to me, however I forget to mention
that my log file also contains some missing / empty values, e.g.
01.01.2017;06:00;419,942
01.01.2017;07:00;513,273
01.01.2017;08:00;478,268
01.01.2017;09:00;
01.01.2017;10:00;606,592
01.01.2017;11:00;
01.01.2017;12:00;594,92
01.01.2017;13:00;524,933

But I could fix this with:
[log_data, comments] =
csvRead(log_file,';',',','double',['.',';';':',';'],"/^[^0-9\-]/");

and using
log_date =
datenum(log_data(:,3),log_data(:,2),log_data(:,1),log_data(:,4),log_data(:,5),0);
mprintf('Log Start:   %d-%02d-%02d at %02d:%02d\n',datevec(log_date(1,1)));
etc...

Subject: [Scilab-users] Shift indices
Message-ID: <1510150051523-0.post@n3.nabble.com>

Hello,
is there a function available to shift indices?
E.g. I have
aa = [1:10]
and want
bb =  6.   7.   8.   9.   10.   1.   2.   3.   4.   5.

This is what I come up with:
log_data2 = zeros(log_data);
log_data2 = log_data(4001:size(log_data,1),:);
log_data2((size(log_data,1)-4000+1):size(log_data,1),:) =
log_data(1:4000,:);

But I'm wondering if there is a prettier solution?

Thanks
richard

it looks that you don't have libtiff.so.4 on your system try download it
from internet (http://www.filewatcher.com/m/libtiff.so.4.16-0.html not
the best souce probably ...) and put it in the directory

/usr/lib/x86_64-linux-gnu/

If you need to shift i = 1:n indices by /any/ p -- not necessarily n/2 
--, you may do

si = modulo(i+p-1, n)+1    // with n = length(i);

Example:
i = 1:10, p = 2;
si = modulo(i+p-1, length(i))+1
--> i = 1:10, p = 2;
  i  =
    1.   2.   3.   4.   5.   6.   7.   8.   9.   10.

--> si = modulo(i+p-1, length(i))+1
  si  =
    3.   4.   5.   6.   7.   8.   9.   10.   1.   2.

Hello,

When I used a script written for 5.4 with 6.0,

I noticed some weird things with the continuation mark "..".
E.g. in 5.4,

"abc...
def"

was OK, it now gives an error ; I have to fix it with
"abc"+...
"def"


Additionally, there should be a space after a * or a / ; *this is not documented*.

This is quite logical as "/." is a different operator.
But "*." Is not an operator.
Only "-." Is documented.

E.g.

--> 5*..
syntax error , unexpected .

--> 5*...
  > 2
Op?ration ind?finie pour les op?randes donn?es.

--> 5/...
  > 2
 ans  =

   0.4545455

I don't understand the result of this later case.

Everything is fine with a space, e.g. "5* .."

I didn't find anything on Bugzilla with "continuation mark" so should I fill in a form?

Indeed, it was not a documented CHANGE in the 6.0.0 release. This 
official change has been added in CHANGES for 6.0.1.

"*." is documented as well:

Scilab > Scilab keywords > star

star - (*) multiplication operator

Description
-----------
  .../...
  A*.B is an operator with no predefined meaning. It may be used to define
  a new operator (see overloading) with the same precedence as * or /.

But i somewhat agree with you: the parser should behave in the same way 
for all dotted
operators. So a report could indeed be filled in, about "*." and ".."

Hmm, actually, i am not so sure that the current behavior is wrong:

That's right, in the way that "*." is parsed before ".."

Unless you have actually overloaded "*." -- have you? --, this looks 
also right.

By the way, with the official 6.0.0 and a later nighlty built for 
Windows, i don't get the same error message. I get the clearer message:
--> 5*...
   > 2
Undefined operation for the given operands.
check or define function %s_u_s for overloading.

Are you using a 6.0.0- pre-release?

n = size(log_data,1);
log_data = log_data(modulo((1:n)-2+4001, n)+1, :);

Yes, it's definitely simpler!

(unfortunately, we can't use the implicit polynomial 4001:$ to replace 
n=.., 4001:n, because it can't be concatenated)

log_data = [log_data(4001:$, :); log_data(1:4000, :)];

In text documents it is good practice to use ? (U+2026) rather than ... 
. Some text editors (Open Office at least) even quietly autocorrect it.
Should it be allowed in Scilab?

Hi Wolfgang,

You could download the CI (Continuous Integration) builds from https://build.scilab.org ; for
example for the 6.0 branch browse the https://build.scilab.org/view/Scilab%206.0/ page. For the
windows x64 build download it as an "artefact" (below the job title) from 
https://build.scilab.org/view/Scilab%206.0/job/scilab-6.0-windows-64/ .

Unfortunately, the nightly builds script (which generates date, timestamps, size information) did
not work anymore after the www.scilab.org migration out of INRIA network. The CI builds let us
iterate more quickly (one build after each commit) than nightly builds (one build each night) ;
using it might be enough for most of us.

Thanks,

Hi

I created symbolic link from missing libtiff.so4 to existing libtiff.so.5.2.4

Then it complained:


atomsLoad: An error occurred while loading 'SIVP-0.5.3.2':
link: The shared archive was not loaded: libjpeg.so.62:
cannot open shared object file: No such file or directory


I did same again for missing libjpeg.so.62 to existing libjpeg.so.9.2.0

Then all hell broke loose!!!


atomsLoad: An error occurred while loading 'SIVP-0.5.3.2':

Really not sure what to try next.

Message-ID: <DB5PR05MB11903DBC35C3E9F9BBB16952C2570@DB5PR05MB1190.eurprd05.prod.outlook.com>


Hello Mac users,


As Scilab 5.5.2 requires a Java 1.5 install, we need to make it think it has one.

Here are steps to run Scilab 5.5.2 on High Sierra:


  *   open a terminal (found in Applications -> Utilities -> Terminal)

  *   note the path returned by:

  *   /usr/libexec/java_home

  *   in my case it returns /Library/Java/JavaVirtualMachines/jdk1.8.0_102.jdk/Contents/Home so in the following commands, replace it with your path. Run the following commands (you'll need sudo rights):

  *   sudo ln -s /Library/Java/JavaVirtualMachines/jdk1.8.0_102.jdk/ /System/Library/Frameworks/JavaVM.framework/Versions/1.5 # Make Java 1.5 point to our install

  *   sudo mkdir -p /bundle/Libraries

  *   sudo ln -s /Library/Java/JavaVirtualMachines/jdk1.8.0_102.jdk/Contents/Home/jre/lib/server/libjvm.dylib /bundle/Libraries/libserver.dylib # Make the requested libserver.dylib file point to our libjvm.dylib

  *   if you get 'Operation not permitted' errors then please consult http://osxdaily.com/2015/10/05/disable-rootless-system-integrity-protection-mac-os-x to bypass macOS protections

  *   at Scilab startup, click on Try Anyway when asked about the macOS version

  *   if you're asked for Java6, follow the steps described at http://www.scilab.org/en/download/latest

Regarding Scilab 6, it is recommended to wait for the next Scilab release which simplifies the launch on High Sierra. Otherwise you may refer to http://bugzilla.scilab.org/show_bug.cgi?id=15307 for a workaround.

Best regards,
Paul

Hello Scilab users,

I'm facing a bug that prevents zooming on a plot inside a frame (or a tab).
Here is my minimum working (or bugging) example:

//////////////////////////////////
// Two axes in one figure:
// left one is inside a frame
// right one is directly attached to the figure
// GUI zoom and zoom_rect don't work on the left plot

h=scf();
h.axes_size=[800,600];
a_right=newaxes(h);
a_right.axes_bounds(3)=0.5;
a_right.axes_bounds(1)=0.5
plot2d()
a_right.title.text="GUI zoom & zoom_rect work here";

frame_left = uicontrol(h, ...
   "style", "frame", ...
   "backgroundcolor", [1 0 1], ...
   "Position", [0,0,400,600]);
a_left=newaxes(frame_left);
plot2d();
a_left.title.text="GUI zoom & zoom_rect DO NOT work here";
//////////////////////////////////

Now come the questions:

1) Did you face the same bug and do you know any workaround to zoom on a plot inside a frame?
2) I plan to report a bug, any advice on the short summary keywords? "zoom not working on plots inside frame or tab uicontrols"?

Cheers,

Antoine

Yes i do on the 6.0 NB-Jenkins of yesterday

> and do you know any workaround to zoom on a plot inside a frame?

Interactively: with the mouse wheel, and then panning (click-hold and drag)
Otherwise: the gca().zoom_box property should work (it does with the wheel).

> 2) I plan to report a bug, any advice on the short summary keywords? "zoom not working on plots inside frame or tab uicontrols"?
Yes. "zoom_rect() can't focus on and fails in a uicontrol frame".

Your example does not involve uicontrol tab. So tabs can't be the cause 
here.
The figure's button runs zoom_rect().

Cheers
Samuel

I know, but this is my minimum bugging example.
In my code, I first encountered this bug with a plot inside a tab.
I think that the bug is present whenever a plot is not directly a children of the figure, but the children of any uicontrol.

Hi
Everything works fine on windows, but unforunately i need to work with linux.
It appears ATOMS has not been configured to run correctly on Linux Mint. This is a real same. Without the toolkits, its reduce capability is a big hit.

Would this be worth submitting as a bug report?

Dear Dave!

I got libtiff.so.4 from Ubuntu Saucy (see this AskUbuntu answer -
https://askubuntu.com/a/457034/66509 ).

Then I installed SIVP with
atomsUpdate(); atomsInstall("SIVP");
from Scilab 5.5.2 x64 on Ubuntu Xenial Xerus 16.04 LTS (as your LinuxMint
is based on it).

As was already mentioned on SIVP ATOMS page - symbolics links are broken
inside SIVP archive (
https://atoms.scilab.org/toolboxes/SIVP/0.5.3.2#comment2775 ) .

So with current SIVP version user should do the following from terminal:

cd /home/$USER/.Scilab/scilab-5.5.2/atoms/SIVP/
0.5.3.2/thirdparty/opencv/linux/x64

rm libavcodec.so
ln -s libavcodec.so.52 libavcodec.so

rm libavformat.so
ln -s libavformat.so.52 libavformat.so

rm libavutil.so
ln -s libavutil.so.49 libavutil.so

rm libcvaux.so
ln -s libcvaux.so.4 libcvaux.so

rm libcv.so
ln -s libcv.so.4 libcv.so

rm libcxcore.so
ln -s libcxcore.so.4 libcxcore.so

rm libdc1394.so
ln -s libdc1394.so.22 libdc1394.so

rm libhighgui.so
ln -s libhighgui.so.4 libhighgui.so

rm libml.so
ln -s libml.so.4 libml.so

rm libswscale.so
ln -s libswscale.so.0 libswscale.so


I'm not SIVP and/or OpenCV expert, I did not use it before your e-mail,
but it seems that it works after aforementioned manipulations.
I can run all SIVP Demonstrations.

Hope this helps.

Could you be more explicit? What's the problem with ATOMS, and with 
which Scilab version?
If you get error messages, which one?

There are some slight changes on this side, despite it is still 
impossible to update existing modules and filesets and to create new ones:
When login, we no longer get neither a blank page without actually being 
logged, nor -- more recently -- getting any red messages about internal 
errors (likely addressed to debuggers).

But there is now a kind of status inversion:
Let's logging. Then, we are directed back to the ATOMS portal with

displayed on the top right corner, and still without any admin rights. 
The strange thing is that
when we then click on "create an account" while we have already one and 
we just tried to logging,
we get on the top right corner

So, we have been actually acknowledged by the loggin process!
Unfortunately, clicking  on Preferences does not lead to the dedicated 
personal page.
No actual page uses the user profile and the SESSION_ID.

This stands also after having removed all old cookies, that could 
prevent a sane ATOMS session after the migration of the ATOMS server.

Regards
Samuel Gougeon

Hola,
I have the following matrix

I have achieved it in the following way.
a (:, [1 3]);
a (:, [2 3]);
a (:, [1 2]);

and in this other way:

a (:, [b (b ~ = 1)]);
a (:, [b (b ~ = 2)]);
a (:, [b (b ~ = 3)]);

But I would like to achieve it using a single index; something like that:
a (:, [column ~ = 2])
Any suggestions,

Hi,

You can try this:
a = [1 2 3; 4 5 6]; 
ix = 1:size(a,2);
a(:,find(ix<>2))

Hello,

Does an implementation of the Radon transform exist in Scilab, similar 
to the Matlab
"radon" function ? Would anybody be willing to share a homemade version ?

Thank you for your input

Hi,

If you are using the Scilab 6, you can consider using IPCV "imradon" 
function.

another implementation in scilab code attached in this email, radon.sci. 
This is pretty slow as it is using a for loop if you were to plot from 
0:179 degree.  this function will need nan toolbox.

hope this helps.

rgds,
CL

Subject: [Scilab-users] The numderivative function consumes a lot of time
Message-ID: <1510757215562-0.post@n3.nabble.com>

Hi;
The numderivative function consumes a lot of time in the calculations.
In the following script I show two options for my "odes" function
In one of them I use the numderivative function; and the calculation is
extended by 9 minutes. And in the other I use the Jacobian determinant of
the function, for each variable, obtained in wxMaxima. And the calculation
is a few, few, seconds.
I am interested in using the function with numderivative, and very similar
to how I have developed it, since it allows me to use it for systems of more
equations.

//Draghilev's Method
clc;
clear;
function Sys=Q(x)
Sys(1)=(x(1)-2)^2+(x(2)-2)^2+x(3)^2-9;
Sys(2)=x(1)^6+x(2)^6+x(3)^6-12;
Sys(3)=x(3);
endfunction
[j,v,info]=fsolve([2;-0.1;3],Q)
ics=j;
//
N=100;
smin=0.0;
smax=0.046;
h=0.001;
*function [dydt]=odes(t,x)
//Scilab
gfd=numderivative(Q,x);
[r,c]=size(gfd)
ic=1:c
for i=1:c
dydt(i)=(-1)^i*det(gfd(1:$-1,find(ic~=i)));   
end
endfunction
*
//from wxMaxima
function dydt=odes(t,x)
    //dydt=zeros(x);
    dydt(1)=-12*(x(2)-2)*x(3)^5+12*x(2)^5*x(3)
    dydt(2)=12*(x(1)-2)*x(3)^5-12*x(1)^5*x(3)
    dydt(3)=-12*(x(1)-2)*x(2)^5+12*x(1)^5*(x(2)-2)
endfunction

    step=smax/N;
    t=[smin:step:smax*N];
    t0=0
    atol=h/100000;
    LL= ode( ics,t0, t,atol,odes)
    clf;
    drawlater()
    param3d(LL(3,:)',LL(2,:)',LL(1,:)');
   
set(gce(),"mark_mode","on","mark_style",2,"mark_size_unit","point","mark_size",4,"line_mode","off")
    drawnow()

Is it possible to decrease the calculation time if I manipulate the options
of% ODEOPTIONS = [*, ..., *]?
What parameters would I manipulate?

Gracias

MicroDAQ Toolbox 1.2v - data acquisition and real-time processing

After over 5000 downloads from Atoms, we are proud to announce the new
release of MicroDAQ toolbox for Scilab. The 1.2v release introduces data
acquisition functionality which enables Scilab users to create advanced data
acquisition applications without a need to use with external tools or
programs. The user can use analog inputs and outputs to acquire data or
generate signals from Scilab. Digital IO (PWM, Encoder, DIO) also can be
controlled with new software.  We also improved DSP code generator by
allowing finite state machine code generation and GUI prototyping with
Evidence E4Coder tools. Improved Xcos block generator allows custom block C
code compilation for DSP and Host which allows block verification before
running on MicroDAQ DSP core. This release can be used with Scilab 5.5.2 and
Scilab 6 on Windows, Linux, and MacOS.

Another possibility :

--> a = [1 2 3; 4 5 6]
 a  =

   1.   2.   3.
   4.   5.   6.


--> foo = a
 foo  =

   1.   2.   3.
   4.   5.   6.


--> foo(:, 2) = []
 foo  =

   1.   3.
   4.   6.

HTH, regards

Hello,

The login issue has been fixed. There were two problems with LDAP 
configuration (due to migration), and session management.

There is still a problem about email sending, probably due to a bad 
configuration on the new server, we are working on it.
But it does not prevent toolbox or file (fileexchange) updates.

Sorry for the delay.

Simon Marchetto

Hi Samuel,
I need the number in "kWh", but no digits after the comma.

Postprocessing with strcat(s," ") is a nice idea.
Is there a function to split the number to the power of 10 factors?
Eg. 2725977 becomes
[2 , 725 , 977]

Then it would be really easy. :-)
Thanks
richard

Thank you all for the replies!

This is my solution now:
// ======== Wrap around at June 1st ========
ix1 = find(log_date==datenum(log_data(1,3),06,01))
ix2 = [ix1+1:size(log_data,1),1:ix1];
dat2 = log_data(ix2,6);

(which is much easier to read :-)

Dear Simon,

it seems that there is still some problem with ATOMS, after uploading new
version of MicroDAQ toolbox isn't isn't visible in Module manage in Scilab
- the uploaded 1.2 version and previous versions are not available.

The 1.2v can be accessed via web:

https://atoms.scilab.org/toolboxes/microdaq/1.2.0

but it is not possible to install it from Scilab with
atomsInstall("microdaq");

The toolbox should be available immediately or server needs to do some
indexing etc and will be available later?

Regards Grzegorz

Hi,



Try this:



// START OF CODE

n = 2725977;

p = int(log10(n));

x=[];

for i=p:-3:0;

    x = [x int(n/10^i)];

    n=modulo(n,10^i);

end

// END OF CODE

Rafael

Eg. 2725977 becomes

[2 , 725 , 977]



Then it would be really easy. :-)

Thanks

Hi,



fscanfMat reads your sample file with not problem:


[log_data, comments] = fscanfMat(log_file)



csvRead has several bugs reported in Scilab 5 series, your case may be one.

Rafael

Hello,

I'm trying to read in a file with whitespace separated values, with

[log_data, comments] = csvRead(log_file,ascii(32),'.','double');

However I'm constantly getting this error:

Warning: Inconsistency found in the columns. At line 2, found 11 columns

while the previous had 5.

but with changing column numbers...



Any clue whats going on?

Hello Simon,

Thanks for your efforts to solve these long standing bugs.
Unfortunately, tonigh, not being logged,

  * ATOMS
      o visiting once the portal is OK
      o visiting any module's page fails and displays: "LDAP : bind ?chou?"
      o after that, visiting again the ATOMS portal fails
  * FE
      o visiting the portal is OK
      o visiting any FS page is OK

  * loggin is NOK : white running page... and finally "LDAP : bind ?chou?"

Aaa, after several attempts and waiting,

  * the page of an ATOMS module gets displayed
  * any login attempt with my usual login displays the red message "No
    account exists for this email"

I did not try to recreate an account at the same login email since it 
could lose all ATOMS and FE pointers formerly attached to this login.

Using space as a column separator is a very bad choice. For instance, in 
the sample that you have posted, the 3 consecutive following rows

> 16800 23200  1  1 10  -3.4 1005 151  4.0 5  2.6  89 1    28 230 -282  2

> 16800 23200  1  1 12  -1.4 1004 148  5.2 4  2.6  80 146    54 245 -289  2

are then read by csvRead() as (if "," were the separator instead)
16800,23200,,1,,1,10,,-3.4,1005,151,,4.0 5,,2.6,,89,,,,1,,,28,230,-282,,2
16800,23200,,1,,1,11,,-3.1,1004,129,,3.5 6,,2.6,,86,,,32,,,70,247,-285,,2
16800,23200,,1,,1,12,,-1.4,1004,148,,5.2 4,,2.6,,80,,146,,,54,245,-289,,2

with many empty columns and a shift, that yields an expected error.
So, there is no bug here from csvRead(). As noted by Rafael, csvRead() 
does not fit to the
job here. Since your data are only numerical, fscanfMat() should work 
instead, indeed.

Hi Samuel,

Not a bug but maybe it could be enhanced for the conversion='double' case by treating consecutive spaces or tabs as a single separator?

Subject: [Scilab-users] The numderivative function
Message-ID: <1511038879500-0.post@n3.nabble.com>

Hi;
The numderivative function consumes a lot of time in the calculations.
In the following script I show two options for my "odes" function
In one of them I use the numderivative function; and the calculation is
extended by 9 minutes. And in the other I use the Jacobian determinant of
the function, for each variable, obtained in wxMaxima. And the calculation
is a few, few, seconds.
I am interested in using the function with numderivative, and very similar
to how I have developed it, since it allows me to use it for systems of more
equations.

//Draghilev's Method
clc;
clear;
function Sys=Q(x)
Sys(1)=(x(1)-2)^2+(x(2)-2)^2+x(3)^2-9;
Sys(2)=x(1)^6+x(2)^6+x(3)^6-12;
Sys(3)=x(3);
endfunction
[j,v,info]=fsolve([2;-0.1;3],Q)
ics=j;
//
N=100;
smin=0.0;
smax=0.046;
h=0.001;
*function [dydt]=odes(t,x)
//Scilab
gfd=numderivative(Q,x);
[r,c]=size(gfd)
ic=1:c
for i=1:c
dydt(i)=(-1)^i*det(gfd(1:$-1,find(ic~=i)));
end
endfunction
*
//from wxMaxima
function dydt=odes(t,x)
    //dydt=zeros(x);
    dydt(1)=-12*(x(2)-2)*x(3)^5+12*x(2)^5*x(3)
    dydt(2)=12*(x(1)-2)*x(3)^5-12*x(1)^5*x(3)
    dydt(3)=-12*(x(1)-2)*x(2)^5+12*x(1)^5*(x(2)-2)
endfunction

    step=smax/N;
    t=[smin:step:smax*N];
    t0=0
    atol=h/100000;
    LL= ode( ics,t0, t,atol,odes)
    clf;
    drawlater()
    param3d(LL(3,:)',LL(2,:)',LL(1,:)');

set(gce(),"mark_mode","on","mark_style",2,"mark_size_unit","point","mark_size",4,"line_mode","off")
    drawnow()

Is it possible to decrease the calculation time if I manipulate the options
of% ODEOPTIONS = [*, ..., *]?
What parameters would I manipulate?

Gracias

Your script makes Scilab 6.0.0 crashing every time it is run => trials 
done only on 5.5.2

  * I get *145 s* by default when numderivative() is called as usual
    from its library.
    Without numderivative(), i get *1.97 s*.
  * After exec(SCI+"/modules/optimization/macros/numderivative.sci",-1),
    this time decreases down to *45 s *only. This is unlikely proper to
    numderivative(). 5.5.2 looks to miss an optimization. For the time
    being, no way to test this on 6.0.0.
  * Your script calls numderivative() ~57000 times.
  * Profiling  numderivative() and its dependencies shows that
    numderivative_evalf() spends a lot of time.
  * Replacing execstr(.., "errcatch") in numderivative_evalf() with
    try/catch, we get***38 s*
  * Then, mainly, vectorizing the function to derivate in order to
    accept x with N columns instead of only 1, and changing
    numderivative() in order to be able to work with this new vectorized
    profile, we get *29 s*.

Improving numderivative() in order to be fully able to work with 
vectorized functions should be possible, but then

  * at first sight it will be less easy to keep it able to run with
    functions that are NOT vectorized (=> back-compatibility issue)
  * The jacobian would become an hypermatrix (OK)
  * The hessian would get up to 4 dimensions

You may post a report on bugzilla in order to point numderivative 
slowness() (if it is not already reported)(Bugzilla is currently off, 
taking its week-end).

This is assuming that the architecture of the current numderivative() 
implementation is kept.
A complete refactoring would be possible. But used for ode(), IMO this 
would not save much of the time spent, since anyway ode() calls the 
function for a single point.

Beside the lack of vectorization, the order is not free. For instance, 
order=3 needs to call numderivative() twice, for instance with order=2 
then with order=1. This limitation is a bit strange.

Hi samuel,
Such good news! to be able to see completely:"Scilab users - Mailing Lists
Archives"

My questions to your answer. Thanks for them:
How can I reproduce this:
"Then, mainly, vectorizing the function to derive in order to accept x with
N columns instead of only 1, and changing numderivative () in order to be
able to work with this new vectorized profile, we get 29 s."

You can guide me with your answer, if possible with an example:
"Improving numderivative () in order to be fully able to work with
vectorized functions should be possible, but then: ...."
  regards

I would very much like to be able to master numderivative. You could guide
me to a website where I can read and study the vectorization in Scilab. I
still do not feel comfortable with it.
Hermes

Hello Hermes,

As stated in my first answer, the only actually valuable thing to do to 
shorten the execution time is
exec(SCI+"/modules/optimization/macros/numderivative.sci",-1)
before the first call to numderivative() (through ode(), in your case).
This will decrease the execution time by a factor of 2,33 (*105s*/45s, 
not 145/45. I made a mistake in my first answer).

But this is not compatible with putting some "clear" instructions 
everywhere, as matlabers do.
Any "clear" clears the redefinition done with exec() and so cancels the 
gain in speed.
So if you are a "clear" addict, you should put it /before/ the exec(). 
Otherwise, each call to numderivative() will use it from it library and 
take 105s (in all) instead of 45s.

I never ever used "clear" (<all>) in my Scilab work for 20 years. I 
don't need it in Scilab,
if it does not apply to some explicitly named variables.

Except the execstr() => try/catch, other modifications = partial 
vectorization are somewhat some hacks,
and the gain is poor, and back-compatibility is of concern. This is why 
i did not attach them to my mail.

It is possible to improve a lot the speed of numderivative() in the case 
of calling it for a whole set of points instead of only a single point 
as currently done. But this  would need to completely overhaul and 
likely rewrite the code.
But this will not be a big gain when calling it through ode(), because 
ode() calls the function with a scalar argument.
With a complete fine profiling, there is likely some room for internal 
optimization of the existing code, but for a marginal gain (IMO less 
than a factor ~1.4 in speed).
With 5.5.2, you can use add_profiling() and showprofile() to analyze the 
code efficiency, as i did. This will show you the parts of the code that 
take most of the execution time, so where to put your efforts to 
optimize it.

Regards
Samuel

Hi all,
thanks for the replies, fscanfMat() does work fine.

I suspected something like this with the changing spaces between the values,
but had hoped csvread would concentrate multiple separators - but then again
in an csv with several ',' one would indeed expect it to treat these as
indvidual columns, so I think the behavior is fine.

Regarding the file format, it is external, so not a choice I have...
best regards
richard

it is right?

Hello Hermes,


If you're using Scilab 6.0.0 the function numderivative is in the differential_equations module so you should use:

  exec(SCI+"\modules\differential_equations\macros\numderivative.sci", -1);


If you want your script to be compatible with both versions you can add:

  v = getversion("scilab");

  if v(1)<6 then

    exec(SCI+"\modules\optimization\macros\numderivative.sci", -1);

  else

    exec(SCI+"\modules\differential_equations\macros\numderivative.sci", -1);

  end


Best regards,

Paul

Hello David,

Did you try with scilab 5.5.2 on the same machine?
There might be a bug in the example with scilab 6.0 as contrary to 5.5.2 we do not interact with the stack.

Hi all,
I have a big matrix, which I want to surf plot. However there are actually
only values for a non-rectangular shape and i want to blank out those other
values (which are -999 by default).

[a,b]=find(M==-999);
M(a,b) = %nan;
surf(M);

However this gives me a weird all-black surf plot, with a Z up to -1000 ??

Am I'm missing something?

%nan are not plotted in Scilab 5.5.2.
Either some data point approaches -1000 or condition M==-999 fails to grab all non-valid entries.

Subject: [Scilab-users] surf and %nan

Hi all,
I have a big matrix, which I want to surf plot. However there are actually
only values for a non-rectangular shape and i want to blank out those other
values (which are -999 by default).

[a,b]=find(M==-999);
M(a,b) = %nan;
surf(M);

However this gives me a weird all-black surf plot, with a Z up to -1000 ??

Am I'm missing something?
cheers
richard

Hi Antoine,

thanks for your comment.
I've just tried on the same machine with scilab 5.5.1 (already installed),
the compilation works fine but link failed:
Error	1	 error LNK2019: unresolved external symbol _inisci_ referenced in
function _MAIN__	callsci.obj	
Error	2	 error LNK2019: unresolved external symbol _scirun_ referenced in
function _MAIN__	callsci.obj	
Error	3	 error LNK2019: unresolved external symbol _matz_ referenced in
function _MAIN__	callsci.obj	

calling convention issue with the underscore ?


Do you where in core module directory I can find the header for the
functions inisci, scirun and matz?

In any case I would like also to call scilab 6 from fortran, under windows,
if you have any other example visual studio project, any suggestion
appreciated ! :) 


David

The syntax is:
M(M==-999) = %nan;
or
M(find(M==-999)) = %nan;

Then

surf(M);

should be OK.

It is not the most compact form but I think there is no issue with original syntax proposed:
[a,b]=find(M==-999);
M(a,b) = %nan;

In the M(a,b) syntax, a stands for the indices of selected ROWS, and b for the vector of selected COLUMNS, no matter about the fact that a and b have here the same length and then could be -- erroneously -- considered as respective elementwise indices.
This is why linearized indices must be used, as returned by i = find(..).

Thanks Samuel for highlighting this non trivial point.
I take it back as the better test here below indicates that the two syntaxes are not equivalent:

x=1:100; y=1:200;
M= x.*.y';
M(10,11:99)=-999;
M(13,13)=-999;
M2 = M;

[a,b]=find(M==-999);
M(a,b) = %nan;

M2(M2==-999)= %nan;

M(isnan(M))=%pi;
M2(isnan(M2))=%pi;

-->max(M2-M)
ans  =
    1283.8584

-->min(M2-M)
ans  =
    0.

Regards,
Rafael

Hey Rafael & Samuel,
thanks for the replies.

However I'm really having a hard time to process this data.
This is the raw data in question:
ftp://ftp-cdc.dwd.de/pub/CDC/grids_germany/monthly/radiation_diffuse/grids_germany_monthly_radiation_diffuse_201601.zip

My minimal script:
asc_list = listfiles('*.asc');
asc_idx = 1; 
asc_file = asc_list(asc_idx);
[asc_data, comments] = fscanfMat(asc_file);
[a,b] = find(asc_data==-999);
asc_data(a,b) = %nan;
surf(asc_data);

Right now it even fails at processing the -999 to nans... It's like I'm
hitting bugs in scilabs?
regards
richard

Hi Richard,



Scilab 5.5.2: had to use stacksize('max'), data loaded but surf would not display 866 x 654 matrix



Scilab 6: it did not work fine with one of the following syntaxes:
asc_data(asc_data==-999) = %nan
surf(asc_data);



or with:

ix = find(asc_data==-999)

asc_data(ix) = %nan

surf(asc_data);



Note that as shown by Samuel and in the test I produced yesterday, the syntax in your original code produces wrong results:

[a,b] = find(asc_data==-999);

asc_data(a,b) = %nan;



To use the indices a,b this should be modified as:

[a,b] = find(asc_data==-999);

asc_data([a;b]) = %nan;



However this last syntax seemed to work on yesterday's test on a much smaller matrix but it is not working on your big one... Not sure if this is a bug or problem with the syntax, needs further investigation.



Regards,

Rafael

[a,b] = find(asc_data==-999);

asc_data(a,b) = %nan;

surf(asc_data);



Right now it even fails at processing the -999 to nans... It's like I'm

hitting bugs in scilabs?

Ok, I corrected the syntax and it works now with regard to the nans:
[a,b] = find(asc_data==-999);
asc_data([a;b]) = %nan;

The black color btw, seems to be from the edge color, if I do
surf(asc_data,'edgecol','white');
it is all white.

How can I turn the egdecolor completely off? preferably via
suh = get('hdl');
suh.edgecolor = 0;
(which doesn't work)

regards
richard


BTW:
I'm usinge Win10 and scilab 6 here at work.
At home I could test on linux and scilab, however I kind of doubt it is an
OS problem.

(sorry for the typo - corrected below. Interesting that the last syntax worked for you on your big matrix, it failed for me on Win 7, Scilab 6.0.0)


Hi Richard,



Scilab 5.5.2: had to use stacksize('max'), data loaded but surf would not display 866 x 654 matrix



Scilab 6: it did work fine with one of the following syntaxes:
asc_data(asc_data==-999) = %nan
surf(asc_data);



or with:

ix = find(asc_data==-999)

asc_data(ix) = %nan

surf(asc_data);



Note that as shown by Samuel and in the test I produced yesterday, the syntax in your original code produces wrong results:

[a,b] = find(asc_data==-999);

asc_data(a,b) = %nan;



To use the indices a,b this should be modified as:

[a,b] = find(asc_data==-999);

asc_data([a;b]) = %nan;



However this last syntax seemed to work on yesterday's test on a much smaller matrix but it is not working on your big one... Not sure if this is a bug or problem with the syntax, needs further investigation.



Regards,

Rafael

Hey Rafael & Samuel,

thanks for the replies.



However I'm really having a hard time to process this data.

This is the raw data in question:

ftp://ftp-cdc.dwd.de/pub/CDC/grids_germany/monthly/radiation_diffuse/grids_germany_monthly_radiation_diffuse_201601.zip



My minimal script:

asc_list = listfiles('*.asc');

asc_idx = 1;

asc_file = asc_list(asc_idx);

[asc_data, comments] = fscanfMat(asc_file);

[a,b] = find(asc_data==-999);

asc_data(a,b) = %nan;

surf(asc_data);



Right now it even fails at processing the -999 to nans... It's like I'm

surf(asc_data);
f=gcf();
f.color_map=hotcolormap(64);
h=get("hdl")
h.color_mode= -2;   //color according to z
h.color_flag= 2;        //remove the facets boundary

Ah, thank you, this looks good!

With my syntax:
[a,b] = find(asc_data==-999);
asc_data([a;b]) = %nan;

I was occasionally still seeing -999 values in the plot (although they
weren't in asc_data), I suspect some memory issues maybe...

However with
asc_data(asc_data==-999) = %nan

it is working on every pass.

Not sure if this should be considered a bug in Scilab 6.0 but it looks odd enough.
If you have time, it might be worth reporting it

This should fix some of Germany's problems:


[a,b] = size(asc_data);
x = 1:a;
y = 1:b;
grayplot(x,y,asc_data)
a=gca();
a.rotation_angles=[0 0];

Nvm, figured this one out. I will just plot a single point on the spot and
then use datatips on this one...

Richard,



It is simpler to properly define the x and y axes and to transpose the input data matrix:


[a,b] = size(asc_data);
y = a:-1:1;
x = 1:b;
asc_data = asc_data';
grayplot(x,y,asc_data)
f=gcf();
f.color_map=hotcolormap(64);

Rafael

At last, after a 5-months-long interruption, the ATOMS server has 
reopened this week! The login works with the former accounts (no need to 
create new ones for authors already having one). The pages to 
administrate modules are accessible.

This is certainly the best piece of news of the month, on the Scilab side.
So, now that some major bugs have also been fixed last summer on the 
ATOMS GUI
side, publishing and updating should be easier on both server and GUI sides,
at least for external modules not requiring to be compiled by the server.

Thanks!

Samuel

Hello Richard,

>Still, kind of 'meh'. Because this way I cannot access the z-value...

You may use param3d() to plot a fake 3D polyline to support and "overlay" datatips.
Then the datatip will include Z by default.
If you are running 6.0: you may also try to use the new .display_components datatip field
https://help.scilab.org/docs/6.0.0/en_US/datatip_properties.html
Never tried Z whether gca().view=="2d". 

>Is there a way to align the text in the box (instead of centered)?

AFAIRemember, it used to be possible with the former datatip implementation up to 5.3 (or 5.4?).
But this feature has disappeared, as still a bunch of other graphic features, since 5.4.
Indeed, this compulsory centering is rather boring, to say few.

fsolve
I find a zero of a system of nonlinear functions:
y = 3 - 10 * x + 2 * x ^ 2 + 3 * x ^ 3 in the range x = -3: 0.01: 3

but fsolve returns as a solution a vector (in the scrip yr) of the same size
as x.
I have varied the precision tolerance h to several values 1.d-3 to% eps. but
I always get that infinity of solutions.
the only solution that I found is shown in the script.
Is it possible to improve this?

 y = 3 - 10*x + 2*x^2 + 3*x^3;

Hi Samuel,
I figured I had to customize the datatip text anyway, so the missing z-value
didn't really matter in this case...

Hello 
The first argument in fsolve is not the range of the variable in which the solution is looked for. Instead it is a guessed value:

// Start of code
function y = poly_cubic(x)
y = 3 - 10*x + 2*x^2 + 3*x^3;
endfunction
 
yr=fsolve(1.3,poly_cubic,%eps)
// yr  = 1.3027756  
yr=fsolve(-2,poly_cubic,%eps)
// yr  =  - 2.3027756  
yr=fsolve(0,poly_cubic,%eps)
// yr  =  0.3333333  
// End of code

By the way, for polynoms, it is more straightforward to do :
p=[3 2 -10 3]; roots(p)
// ans  =
  - 2.3027756  
    1.3027756  
    0.3333333

<https://ljk.imag.fr/membres/Bernard.Ycart/mel/ds/ds.pdf>  , on page 36.
 I find it interesting to introduce a range as an initial value.
I use  otras funciones y obtuve los resultados esperados.
function y=f(x)
    y=exp(-x.^2)*cos(4*x);
endfunction
function y = B(x)
 y = besselj(40,x+cos(x));
endfunction
I would have liked to replace this script with the fsolve function:

function root=brute_force_root_finder(F, a, b, n)
    x = linspace(a, b, n);
    n=size(x,"*")-1;
    y = feval(x,F);
    root = [];
    for i=1:n-1
        if y(i)*y(i+1) < 0 then
            root($+i) = x(i) - (x(i+1) - x(i))/(y(i+1) - y(i))*y(i);//root =
x[i] - (x[i+1] - x[i])/(y[i+1] - y[i])*y[i]
        end

Hello,
I am not convinced that in the quoted document the first argument is a range:
the values returned by the function fsolve are generally not lying in the intended "range";
if you try: 
fsolve([0.4,0.45,0.5],f)
 ans  =
   - 1.    6.    228.
If I understand correctly, the first argument is considered as a vector, i.e. that the function f takes a vector as argument and returns a vector of the same dimension, with elements sin(2*%pi*xi). 
In any case, it is quite strange to give 0.5 as initial value for this search of root, as at this particular point f=1 and its slope is zero !!! It explains why very strange values are returned for the roots.

Denis

This is a strong indication that Scilab is trying to solve a problem in the 401-dimension space (as opposed to solving 401 equations in 1D) when you give the vector 0:0.01:4 as first argument, as I suspected in my previous message.
In addition, I stress the point that looking at the result returned by fsolve, the roots are not contained in the so-called "range" that you think you define in the first argument of fsolve: either fsolve has a bug, or the first argument you give is NOT considered as a range, whatever expression you use.
Best regards
Denis

You are all right, Denis.
But this feature could actually be used to parallelize computations of 
several roots, provided that the function is well vectorized. But it's 
not the case: there is a mistake:
Le 28/11/2017 ? 11:58, Hermes a ?crit :
> .../...
> function y=f(x)
>      y=exp(-x.^2)*cos(4*x);
> endfunction
.* cos() should be used instead of *cos()

Le 28/11/2017 ? 11:12, Hermes a ?crit :
> .../...
> function y = poly_cubic(x)
>   y = 3 - 10*x + 2*x^2 + 3*x^3;
> endfunction

This one is definitely not vectorized. .^should be used instead of ^.

Hello,
when trying to read in this file:

with:
M = fscanfMat('grids_germany_monthly_radiation_direct_201706.asc')

I'm getting an error message. I suppose there is something wrong in that

Not directly a Scilab problem (except for the fact that the 'fscanfMat'
error message could be more verbose), but maybe someone here has an idea how
to find the error...

Thanks

When the header is stripped off, there is no error:
M=fscanfMat('grids_germany_monthly_radiation_direct_201706.asc');
 
-->size(M)
 ans  = 
    866.    654.

Hey all,
@Denis
Very strange. For me it doesn't change if I strip the header of or not, I
get both times an error...

@Samuel
For me it unpacks a ~3 MB big file.

@Eric
yes, I'm unzipping them ...

This is what I get when using csvRead. It seems to be OK up to row? 
558(after the header) - I renamed the file t.txt.

mmm=csvRead("t.txt"," ",[],[],[],[],,28);
Warning: Inconsistency found in the columns. At line 559, found 1307 
columns while the previous had 654.

csvRead: can not read file t.txt: Error in the column structure

It has to do with the line length , try to replace -999 with -9

I confirm. After using another web browser to download the file,
and after removing the header, fscanfMat() works like a charm.

In Win7 Scilab 6.0.0  it only worked with Jan's recommendation (replacing -999 to -9), with or without header.

The original file seems to have numeric data lines with total number of characters varying from 3270 to 4172 per row.

There must be a limitation somewhere, in Windows or Scilab 6.0.0 ?

Actually, just making? sure the first data line the longest seems to 
work too, for instance by adding spaces to it.

Same for me with or w/o header doesn't matter. However either replacing -999
by -99 or adding 859 Spaces to the first line, makes it readable for me....

Win 10-64bit, Scilab 6.0

Subject: [Scilab-users] guibuilder 4.1/4.0.1 reload problem
Message-ID: <1511987960186-0.post@n3.nabble.com>

Hello guys, 

Recently I tried to create a GUI in scilab using guibuilder. I could save
and run the GUI, but the problem occured when I was going to open the GUI
via guibuilder to make some changes. I got a message:

operation -: Warning adding a matrix with the empty matrix will give an
empty matrix result.
operation +: Warning adding a matrix with the empty matrix will give an
empty matrix result.

What I found until now is (unfortunately) a not working solution on this
site (comment lines): https://atoms.scilab.org/toolboxes/guibuilder.

My OS is Windows 10 Home (x64). My scilab version is 6.0.0 (x64).

So far I have tried to solve this problem in the following ways:
1. Install guibuilder with tools -> atoms manager. 
2. Console -> atomsUpdate('guibuilder').
3. Console -> atomsInstall(["guibuilder" "4.1"]).
4. Delete the scilab\contrib\archieves folder and install guibuilder again.
5. Download guibuilder-4.1-bin.zip file and manually place it in
scilab\contrib\archieves.
6. Install the x32 version and try the above ways.

Every method i tried to install the guibuilder says that version 4.1 was
installed, but when I launch the builder it shows 4.0.1.

I would be really grateful for your help.

Cheers

Yes, this is reported here: 
https://atoms.scilab.org/toolboxes/guibuilder#comment2836
You may reply to this ATOMS comment to stress the authors about this issue.
You can also enter
--> warning stop
before using the module. This will yield an error message (instead of a 
simple warning) indicating the script and the line number where the 
issue is located.
Then, you can edit and fix the right script yourself, if the authors do 
not do it quickly.

Hi:


First of all, i cannot run scilab 6.0 in Ubuntu 17.10, gives GTKLookAndFeel error that was adressed in the past, but not resolved.


Second, in my Ubuntu 16.04 PC, scilab 6.0 gives seg fault when trying to use bode function.


And last, is there a way to simulate a trasnfer function with delay using csim? i'm using pade aproximation by hand right now...

Hello Samuel,
thank you for your reply.

Due to an register issue I couldn't comment on ATOMS site, so I will try
later.
Following your advice I've tried to enter /warning stop/ in the console
window, but nothing changed. The warning message still appears, and the
error message doesn't, so I can't find the faulty script. Searching on my
own I found in macros a open_existing_gui.bin file, but everything seems
fine here.

Am I doing something wrong with /warning stop/?

Hi Rafael,
This is how I have reproduced your guidelines:
*========
funcprot(0);
function val = H(x1, x2) 
    val=(1.25*x2-sqrt(abs(x1))).^2+x1.^2-1;
endfunction;
function m=g(x1,x2)

m=[2*x1-(x1.*(1.25*x2-sqrt(abs(x1))))/abs(x1).^(3/2),2.5*(1.25*x2-sqrt(abs(x1)))];   
endfunction

function val = HH(z) 
    x1=z(1); 
    x2=z(2); 
    val=(1.25*x2-sqrt(abs(x1))).^2+x1.^2-1;
endfunction; 
function z=dH(x)  
z=numderivative(HH,x) 
endfunction 

//test 
xx=[0.2 -0.5];
disp(H(xx(1),xx(2)));
disp(g(xx(1),xx(2)));
disp(dH(xx));

x = -1:0.01:1;
g1=g(x,2*x)
contour2d(x, 2*x', g, [0 0]);

replot([-1.415,-1,1.415,1.415]);


//expected values
//x1 -0.5566931 y1 1.2614695
//x2 0.5566931 y2 1.2614695
//x3 0. y3 0.8
//x4 0. y4 -0.8
//plot([x1 x2],[y1 y2],'gd');
//plot([x3 x4],[y3 y4],'rx');


========
*
but in spite of the fact that the help for abs can be read:
"absolute value, magnitude
Syntax
t = abs (x)
Arguments
x real or complex vector or matrix "
I receive the following alert:
  "Function not defined for given argument type (s), check arguments or
define function% function_abs for overloading."

should I define the function mabs = sqrt (x1 ^ 2 + x2 ^ 2);

And using only the function g in contour2d (x, 2 * x ', g, [0 0]) I also
receive the following alert:
---> in builtin contour2d (C: \ PROGRA ~ 1 \ SCILAB ~ 1.0 \ modules \

g: Wrong size for output argument # 1: A Scalar expected.

Any help, correction or markings

I also get with 6.0.0+:
--> contour2d(x, 2*x', g, [0 0]);
in builtin                contour2d ( SCI\modules\graphics\macros\contour2d.sci line 12 )

g: Wrong size for output argument #1: A Scalar expected.
??l: An error occured in '?????' subroutine.

Hi Hermes,



I do not recall your problem and it would help some explanation.

To plot the contours of a gradient with contour2d, you have to make it a scalar (otherwise look at champ, etc.).

Check out the edited code below.

Note that your gradient does not reach 0 and so a contour |g|=5 is plotted.



// START OF CODE

clear; clf;

funcprot(0);

function val=H(x1, x2)

    val=(1.25*x2-sqrt(abs(x1))).^2+x1.^2-1;

endfunction;

function [gx, gy]=g(x1, x2)

   gx= 2*x1-(x1.*(1.25*x2-sqrt(abs(x1))))./abs(x1).^(3/2);

   gy = 2.5*(1.25*x2-sqrt(abs(x1)));

endfunction



function val=HH(z)

    x1=z(1);

    x2=z(2);

    val=(1.25*x2-sqrt(abs(x1))).^2+x1.^2-1;

endfunction;



function z=dH(x)

    z=numderivative(HH,x)

endfunction



//test

x0=[0.2 -0.5];

disp(H(x0(1),x0(2)));

[gx,gy]=g(x0(1),x0(2))

disp(gx,gy);

disp(dH(x0));



x = linspace(-1,1,1002);

y = 2*x';

xx = x.*.ones(x');

yy = y.*.ones(y');

[gx,gy] = g(xx,yy);

g1= abs(gx + %i*gy);

contour2d(x, y, g1, [5 5]);



replot([-1.415,-1,1.415,1.415]);

// END OF CODE

Message-ID: <1512070541640-0.post@n3.nabble.com>

Hey everyone


I kept on trying to find out what the error is in the code below, but can't
seem to find it. Even weirder is that among my colleagues I am the only one
who gets a different output than the solution with the same code. 



temp=csvRead("the path to the file/meas0001.csv", ascii(9),
'.','string',[',' ' ']);   // to read the csv data
temp(1,:)=[];  // to remove the first line
temp($,:)=[];  // to remove the last line

The output I get :

The "supposed to be like this" output is with only the same numbers, but
without the "Vac", the dates and the times in the first and last row and the
exclamation marks. 

I'd be flattered, if someone could help me out.

I have installed this module with Scilab 6.0.0+ for Window_x64 without 
any issue,
including the call to
--> guibuilder
with no warning. So, these warnings and the final error occur when 
opening the actual GUI
that you have created. It is hard to reproduce and help debugging 
without the actual GUI's file.

I get as well this "4.0.1" in the title of the GUI. I think authors have 
just forgotten to update it,
but the version is actually the 4.1 one. I would not take care about this.

The warning occurs no matter what gui file i try to open. I can create a new
gui, I can save it, I can run it, but I cannot open it to add changes.

> It is hard to reproduce and help debugging without the actual GUI's file. 

This is an example of a gui file I created with my guibuilder: 
https://drive.google.com/open?id=1c8OoHmNSgC8-lNkBkkITUnC99EPj44hV
There should be only a button called "Test" which displays in the console a
message 'test'.
