I have made a toolbox and added lines like this;
SCI_CS = 'U:\SciLab\'
load(SCI_CS+'cs_signal\macros\lib')
...in my scilab.star file. It seems like the functions are loaded into

I have been  compiling the Scilab 5 svn version since several weeks
ago and I get always the same error when trying to plot something.
I am using a Kubuntu 7.10 linux.
Thanks

Hi guys, I'm running an openSuSe 10.3
After checking out, configuring and making; when I issue a make
install command I get this error:
hansolo2:/opt/scilab-trunk # make install

when I try and run scicos on my freshly built scilab 5 (svn updated
today) I get this error:
donato@hansolo:/opt/scilab-5/bin> Could not instantiate the object org/
scilab/modules/renderer/figureDrawing/DrawableFigureGL with the

I'd like to report what appears to be a bug in Scicos 4.2 (both
Windows and Linux versions).
I use the context to define the simulation variables to be used in the
blocks and in the simulation set-up. One of these variables is tf,

I'm new in scilab and using this nice tool to plot some data.
The problem I have is that I use scilab under Windows _and_ Linux. I would
like to create an batch file/script to launch scilab with an specific
sce-file. This sce-file opens the data file in the same directory like the

I can't find how to have a label containing exponent in a scilab
figure. Is it possible? do you know how?

  I would like to set an environment variable (FOO) that contains the path to a directory in
my file system (/tmp/foo). I would be able to use it in the same way I do with SCI or TMPDIR,
e.g cd SCI/, cd TMPDIR/, exec SCI/contrib/a-toolbox/loader.sce etc. I define FOO as follows:
...

I've got printing issues .
I've created a "mlist" named "mypoly".
The type "mypoly" is equivalent to the polynomial type with
coefficients which alredy are "mlist", named "mycoeff".

I would like to find the minimum of a multiple variables non-linear
discrete function, and I'm not a mathematician...
More specifically: I have a few hundreds thousands of data points
(X1,X2,...,Xn,Y) where the Xn are the variables and Y is the result of

hi, all. My name is Aviv. I simulate scicos diagram in batch mode by
use "scicosim" function. I write this syntax :
     [state,t]=scicosim(state,t0,tf,%cpr.sim,'start',tol);
     [state,t]=scicosim(state,t,tf,%cpr.sim,'run',tol);

when I star scilab, appears this message...
Startup execution:
 loading initial environment
!--error 241

Is there a way to place free text, or is there an empty block that I can
type notes in, or is there another way that I can annotate a block
diagram in Scicos?
Thanks.

I have a simple MatLab program that has been written for us to do some
very basic image processing.  We own the copyright to the software,
but don't have a MatLab license (the subcontractor did).
I have two tasks (1) To demonstrate the concept of the image capture

Does anyone knows a method to return the symbolic variable of any
polynomial ?
For example, I create
a =poly([1,2,3],"s","coeff")
