I dont quite know how to phrase this problem so if it is too unclear
just tell me...
I am trying to use ode to solve for a system of differential eqs but I
need the state variables to be restricted to a value.

hello!!!
I'm trying to convert simulations using MATLAB-SIMULINK with SCICOS in SCILAB.
I'm stuck up at de point of creating blocks for discrete filters.
Could anybody please help me in telling how to block for this type of

I am a beginner, and it is the first time i install scilab. after
installation i got this on the scilab

under SCILAB?

whenever i open scilab, run some demos in graphic catagory, some
annoying messages will be displayed in terminal:
Scilab : X error trapped - error message follows:
BadWindow (invalid Window parameter)

I want to simulate a closed-loop position control system in state-
space representation using syslin and csim, but I want to be able to
adjust proportional gain downward to reflect the maximum output
current limit of a power amplifier.

I am using SciLab and MATLAB together since quite a long time now
(taking advantage of both).
Until now I have been passing datas from one to another by means of
*.mat files which was sufficient. I am wanting to make Scilab and

from the online help, the function string applied to an other function
should return output and input variables, and the source code of the
function.  In the example below (with scilab 4.1.1 under windows Xp)
source code of f is not returned :

I am running Labview 8.2(soon to be 8.5), Scilab 4.1.1, Sci-LV Gateway 1.0
How does one call an external function? Any script where I try to call a user
defined function just gets caught in an error loop...or does nothing(i.e. the
vi runs, but the front panel indicator does not ...

Is there a way for me to use a later/modified version of Tcl/Tk with Scilab?

Scilab crushes randomly, but quite often (30%?) when I run following
program, may be  especialy when I change some parameter and run the
program without having closed the graphic window. If I close Scilab
after crush and reopen it, the program works without I have to change

In the help about Sfgrayplot, explanations about strf option are said to
be searched in the plot2d help article. In fact there are to be searched
in the plot2d_old_version article.

I updates the newest version and compiles Scilab-svn EVERY DAY, but I
have NEVER get a successful result.

Today the error message is:

I renamed the console library in the thirdparty directory because it was
badly named.
Then
Console-1.0-API.jar => Console-API-1.0.jar

Ive got 2500 datapoints in a csv showing an oscillatory response
overlaid over a general trend towards zero. I need to find and plot
that trend - whats the best method of doing it? I've scouted out the
help file but it doesnt help too much! I find the documentation is
