Bonjour,

unfortunately is not yet possible run Scilab and Scicos at the same
time like Matlab/Simulink, but you can obtain the same results using
this technique:
- prepare a Scilab script that contains all the physical parameters of
  the electrical machine (like Ls, Rs, Ms, etc.) the algorithm used to
  design the controller (PID, state space, fuzzy, etc.).
  Use this script to fill some Scilab variables like A,B,C,D and F matrix
  or Ki,Kp,Pd 
- run "scicos();": prepare a Scicos diagram that model the machine and
  the controller using the above variables instead than numerical 
  parameters.

There are two additional techniques:
- you can "incorporate" a Scilab script _inside_ Scicos using the "contex"
  feature. Using the "internal" Scicos context the Scilab design script
  will be stored inside the Scicos diagram;
- you can run a Scicos simulation from a Scilab script using:
  Info=scicos_simulate(scs_m,Info[,%scicos_context][,flag])

  Please see the Scilab help for more details about this two features.

Do not hesitate to ask for more help: I was exposed to Clark and Park
transformations when I was young :).

Hi, 

I get the error below. I think scilab-bin is missing from the repository. 

The following packages have unmet dependencies: 
scilab: Depends: scilab-bin (= 5.0.3-6ubuntu1) but it is not going to be installed

Try to remove scilab 4.X first.
aptitude purge scilab && aptitude install scilab

I think I fixed this bug in later version of the packaging of Scilab.

Hi Sylvestre,

I have purged all packages related to scilab and still get the error.  It is still trying to install scilab-bin.  Does this exist in 5.0.3?

Thanks

Dear Scilab User group

I'm a complete beginner to Scilab and I have little knowledge of this 
kind of software. My main requirement is to be able to use a Neural 
Network, Principle Components Analysis and Genetic Algorithm toolbox. I 
really have no idea where to start and I would appreciate any advice you 
could give on becoming familiar with the software as soon as possible. 

My intended purpose is for research. I'll be doing feature selection, 
using both PCA and GA. And then finally pattern recognition using a 
neural network. If you could help I would me most grateful.

Best regards

Hello,

For the genetic algorithms: you can check
http://wiki.scilab.org/Genetic_algorithms.
Try also 'help optim_ga'. This will open the help browser on the main
genetic algorithms method.

PCA: 'help pca' will open the help browser on the pca function. There is a
simple example of use on this page. You can first try a copy paste.

For Neural networks:
try to install the ANN toolbox:
http://www.scilab.org/contrib/index_contrib.php?page=displayContribution&fileID=1112

you can try also the lolimot thing. It's a variant of neural networks
(called fast neural networks):

Hello,

I am trying to use a jar form scilab into a Windows Java application,
but have integration issues.
I added org.scilab.modules.graphic_export.jar into one of my Eclipse
projects. To be able to use its classes, I had to modify the
environment variable PATH and add the scilab bin dir. Until now, all
was ok.
Now I want to get rid of this update by setting java.library.path
instead (by adding VM arguments from the Eclipse execution parameters
tab) with what I appended into the PATH. This had to work, but I am
getting this error:
The native library scigraphic_export does not exist or cannot be found.

Message-ID: <alpine.OSX.1.10.0904150843320.410@fchq.ybpny>

Hello Scilab users.

I recently installed scilab-5.1.1-alpha-1 on an Intel Mac Pro, running
Mac OS X 10.5.6.  I've had some difficulty getting the application to
launch.

When I double-click /Applications/scilab-5.1.1-alpha-1.app, the
program icon appears in the Dock for a few seconds, then disappears.

Trying to run Scilab from the command line shows that the problem is a
library load error.

   $ /Applications/scilab-5.1.1-alpha-1.app/Contents/MacOS/bin/scilab
   Could not load JVM dynamic library (libjava).

   Scilab cannot open JVM library.

I see the same results with scilab-5.1.

After some trial and error, I think I've found the cause of the
problem.  On this machine, Java 1.6 is configured as the default Java
version (I need Java 1.6 for development work).

   $ java -version
   java version "1.6.0_07"
   Java(TM) SE Runtime Environment (build 1.6.0_07-b06-153)
   Java HotSpot(TM) 64-Bit Server VM (build 1.6.0_07-b06-57, mixed mode)

It appears that Scilab doesn't work with Java 1.6's libjava.  But, I
can get Scilab to launch by doing the following:

   env DYLD_LIBRARY_PATH=/System/Library/Frameworks/JavaVM.framework/Versions/1.5.0/Libraries /Applications/scilab-5.1.1-alpha-1.app/Contents/MacOS/bin/scilab

I have two questions as a result

  - Am I correct in concluding that the Mac OS X Scilab 5.1.1 works
    only with Java 1.5, and not Java 1.6?

  - If the above is correct, is there a preferred method of telling
    Scilab to use a Java version that's not the system default?

Thank you for any assistance.

Steve Revilak

That means it needs the library libscigraphic_export.so to be available
in the java.ld.library.path.
(it contains the jni functions).

Can I ask what are you trying to do ?

Hmmm, I believe it is more due to a bad assumption from me about the
place where Apple is storing java native libraries.
I have to update my script to fix it.

I am going to write a patch to fix it (next week ?). I will probably ask you to test it!

The package is docbook-xsl. You can remove other.

The list of the dependencies is available here:

Maybe you can try the configure flag --with-docbook=path
or you can download the thirdparty from the scilab website and copy 
everything in scilab-5.1.1/thirdparty

Hi, all.

I am using Tylor series method for matrix exponential computation. But
after reading [1] I'd like to switch to better method.

MATLAB uses a scaling and squaring algorithm with a Pade approximation,
which is described in [1] as well.

Scilab uses first block-diagonalizing and then applying a Pade
approximation on each block.

1. Should I use Scilab expm function or MATLAB algorithm?
2. Which file contains source code for Scilab expm function?
3. Where I can find description for Scilab algorithm.

Thanks.

We are not aware of such request but we would probably say yes anyway! 
Good luck with your forum!

Subject: Link between scilab and c program
Message-ID: <257849.36124.qm@web52710.mail.re2.yahoo.com>

Hi,

I want to create a C program that executes a function inside Scilab.

I use Scilab 5.1.1 in Kubuntu, gcc 4.3.2

I create a simple function in C to try this.? The name's program is 'dados_para_scilab.c' :

double funcao(x)
double *x;
{
? double result = (*x)+1;
}//end function

Then, I compile:

gcc -o dados_para_scilab.o -c dados_para_scilab.c

And I put the 'dados_para_scilab.o' file inside the work directory that I defined for Scilab (with 'chdir' command).

Then, inside Scilab:

--> link('dados_para_scilab.o','funcao','c')

But the following message is showed:

Link failed for dynamic library 'dados_para_scilab.o'
...only: ET_DYN e ET_EXEC can be loaded.
link: The shared
 archive was not loaded: (null)

What am I doing wrong? Someone could help me? It would be a great value to put some C code and the steps to make this working.

Thanks in advance,

Lucio

For the compilation of your program, try this:

gcc -shared -o dados_para_scilab.so -c dados_para_scilab.c

You must build a shared library instead of a classical object.

the .o is misleading. It is the name of the target.

You can delegate the build to Scilab:

For example:
f1=['int ext1c(int *n, double *a, double *b, double *c)'
    '{int k;'
    '  for (k = 0; k < *n; ++k) '
    '      c[k] = a[k] + b[k];'
    '  return(0);}'];

mputl(f1,'fun1.c')

//creating the shared library (a gateway, a Makefile and a loader are 
//generated. 

ilib_for_link('ext1c','fun1.c',[],"c")

Is there a Web Service Client toolkit for scilab?
Or is such a toolkit under development?

I'd be really grateful for any information.

AFAIK, there is no such thing available for now.
We will probably work on this in the future but I don't see that coming
in the few next months ...

What kind of webservice client are you looking for ? XML-RPC, SOAP or
REST ?

Thanks for the information, I would like to be able to build a soap1.2 
client
Would it be possible to link clients developed using the gsoap tool kit 
with scilab?

cheers
