I'm a very beginner with scilab and scicos. So now I'm looking for
functions like the analogin- /-output, digitalin- / -output functions in
MATLAB. I'd like to interface my soundcard directly to scilab functions or
scicos blocks.

G'day all (Bonjour):
  Please forgive if this has been asked before.
  Is there a repository of functions somewhere akin to Matlab's
symbolic manipulation functions... such as...

Given an array of angles (between 0 and 360 degrees) I want to plot
something that looks like this image: http://www.eyra.se/temp/angleplot.png
The black segments are for angles that are in the array.
Can that be done in scilab? How?

First, let me introduce myself. My name is Aviv Siswanto. I am student
of Bandung Institute Technology, Indonesia.
I am currently trying to simulate control  system  using scicos 4.11
in batch mode. But, when I stoped simulation by gave event signal to

Hello group,
  I'm writing to report an issue with function ilib_for_link in Scilab 5. My operating
conditions are the following:
    - O.S.:     Ubuntu 7.10 - the Gutsy Gibbon

I am currently trying to interface a fortran function. In this fortran
function, the parameters are in a common. How do I set the variables
in the common from a C function ?

Hello group,
  The following are my operating conditions:

The current version of XMLLab does not seem to work well with Scilab
4.1.2. it does install, however with a few warnings. However,
subsequently one is not in a position to load SCICOS.
I have one request for the next release of XMLLab. This is again re.

I am trying to implement some simple mechanical blocks using Generic
Modelica Blocks. My problem is I defined a new connector type called
Flange, which is similar to an electical pin.

I have started to learn how to use the signal processing routines in
scilab, by first plotting some filter responses as exercise, and have
found the following behaviour of syslin:
z = poly(0,'z');

Is there a function for 2D convolution in scilab?
Cheers,

I've tried using wfir, and i know how to set it to lowpass mode and to
set
its cutoff frequency and slope. However, once I set these values, how
do i apply the filter to a signal?

I'm getting quite a headache using the matrix palette of scicos. I
have the following problem : I'm implementing a RLS algorithm, where
at some points I need to multiply my covariance matrix (dim : nxn) by
a scalar , namely a gain that is not constant but calculated. Simply

I've built and installed the last revision of scilab-5 and I just
noticed that the documentation is not installed.
How to build and install the documentation ?
