I have a problem with batching scicos in scilab. I have my diagram
with its own context
            if ~exists('w0') then w0=1, end                etc....
(w0 is a parameter in a superblock)

can anyone tell how to arrange , say a 2x2 matrix along the diagonal
to give a 4x4 matrix with all elements except the smaller matrix
zero ?
eg :   2x2 =[1 2

Do you know where I can find the latest scilab.el for
editing/loading/launching scilab from an Emacs window ?

 Question about scicos:
In simulink we have a function that set's up the sample time for the
integrator, within the time interval between sample times the function
that calculates the outputs are not called and outputs are considered

I'm having a strange behavior with a compiled block in scicos, maybe
I'm doing something wrong, but it can also be a scilab bug, that's the
reason for my post.
Scilab 5.0.1 for windows

hello, everyone,
i used a scicos model that someone gave me to examine it. and i want
to know how to fonction each block and hope to debug them.
How can i do?

Where do you upload Sicos example models? I have implemented a
Induction motor d-q model in Sicos, which I want to share.

Does anyone have a script that connects to the YAHOO finance server

I have just installed Scilab 5.0.2 on my PC running under
Fedora 9.0 (recently updated). Scilab seems to run OK.
However all requests for plots will only show a blank
(black) plot window. Has anyone else had this experience? Is

Does anyone use this? It doesn't seem to really be support by the
Scilab group.

I've tried the version 5.0.2.
I used to use the input function to ask question to user. For prettier
appearance, under version 4.1.2, i use "\n" to introduce a line feed.
This seems to not run correctly anymore.

Like other, I am not too fond of Scilab-5's dependency on Java.
As far as I noted there was a fork for Scilab-4 + gtk, now called NSP.
Correct me if I'm wrong, but I think some (important) developers (e.g. of Scicos)
have turned to NSP.

I would like to compute the eigenvalues of a sparse matrix.  The
Arnoldi package is apparently already included in Scilab 5, but the
wrapper function "eigen", which was available in the Arnoldi toolbox
from     Antonio Frasson, is missing.

I'm pretty new to Scicos and want to model a resonator in Scicos.
I'm using a "Continuous transfer function" block and that works well.
Here's the challenge that I'm facing:
At a certain point in time during the simulation I would like the

I have got two questions about Scicos.
1. How can I deliver any parameters of my simulation model from scilab
to scicos? In matlab is it possible to use sim('simulink
application'). Is there a command? Because I want to control my
