a quick and dirty hack for the function bar : bar.sci You could put any colors from the color_list help page and even colors in form "[R,G,B]" (a rgb vector inside a string) with r,g,b integer values in [0,255]).

The scispt toolbox (scilab sparse tools) version 1.4 : this is a Scilab interface onto the UMFPACK package v5.0 or v4.3 of Tim Davis and the TAUCS snmf Cholesky solver of Sivan Toledo plus some sparse utility scilab macros. (for scilab >= 2.7).

This toolbox has been integrated in the scilab core since version 5.0 but it could be useful if you use scicoslab or a scilab 4.x

on Unix get this archive : (SCISPT_v1.4.tgz) (note : the archive size (1.24 M B) is due to the inclusion of 4 Harwell-Boeing matrices for the demo)
version 1.2a (for umfpack v4.0) may be get here: (SCISPT_v1.2a.tar.gz)
version 1.1a (for umfpack v3.x) may be get here : (SCISPT_v1.1a.tar.gz)
you can see a small bench which shows the improvement brought by this toolbox over what is already interfaced in scilab to solve general sparse (Sparse1.3) matrices (the bench file) (see the slides for some results with the TAUCS snmf (super nodal multi frontal) Cholesky solver).

here are the slides of my talk about SCISPT at a meeting about sparse computations in scilab (presentation of scispt)

A CmapUtility : I have coded a scilab tool to design colormaps in a easy way, current version is 0.95 toolbox : for scilab >= 3.0 (on Windows it works only with recent instable versions (from March 2005) which include the fix for bug 1159). Note : you cannot use it on scilab-5.x (the old graphic system being removed since version 5.0).

on Unix get this archive : (the tgz archive)

on Windows get this one: (the zip archive)
