Ceux qui connaissent bien les logiciels libres (généralement sous licence GPL) peuvent s'interroger sur le statut de Scilab en tant que logiciel << libre et gratuit >>. Voici ce qu'en dit le Doc dans un message posté sur le forum :
Scilab: is it really free?Yes it is. Scilab is not distributed under GPL or other standard free software copyrights (because of historical reasons), but Scilab is an Open Source Software and is free for academic and industrial use, without any restrictions. There are of course the usual restrictions concerning its redistribution; the only specific requirement is that we ask Scilab users to send us a notice (email is enough). For more details see Notice.ps or Notice.tex in the Scilab package.
Answers to two frequently asked questions: Yes, Scilab can be included a commercial package (provided proper copyright notice is included). Yes, Scilab can be placed on commercial CD's (such as various Linux distributions).
