New scientific features & Performances of linear algebra

[Michaël Baudin]

Hello,

We are often asked about the new computational features of Scilab. The 
CHANGES file associated with each release provides some information, but 
it mainly focuses on the updates and does not provide the context of the 
new features. Moreover, this does not give any informations about the 
external modules, provided by ATOMS, for example. This is why we have 
written the wiki page :

http://wiki.scilab.org/New_Scientific_Features

The goal of this page is to focus on the new scientific, computational 
features in Scilab. This document aims at presenting a short abstract of 
the each new module along with the changes that were made to it. This 
allows to gather the various developments which are made both inside 
Scilab and outside Scilab, for example as external modules. By this 
mean, we can have a knowledge of the computational algorithms and 
functions which are available in the Scilab environment, in a broad 
sense. The presentation is based on a year-by-year analysis, from 2008 
to 2010.


We had recently the opportunity to check the performances of linear 
algebra in Scilab. In order to gather the best performances which can be 
obtained with linear algebra algorithms provided in Scilab, we have 
created the page :

http://wiki.scilab.org/Linalg_performances

In this page, we present performance of various Scilab scripts involving 
linear algebra. We emphasize the use of Mflops as a measure of 
performance of linear algebra routines used in Scilab. We consider here 
two benchmarks:
  * the dense, real, matrix-matrix multiply,
  * the solution of dense, real linear systems of equations.

These wiki pages are designed to be improved by anyone willing to. 
Please insert directly any information that you would like to publish.

Best regards,

Michaël Baudin
