Salut, I am deeply interested in using an open-source symbolic computation kernel under applications such as Matlab (and to keep open, Scilab and Octave). I think this would be an alternative to (very) expensive solutions proposed by The Mathworks, to build it upon GiNaC. A few questions then: * is there a manner of doing this by implementing a kernel usable for the three softwares mentionned, and developping specific code only for interfacing ? * are there any legal problems since such a toolbox exists under Matlab (built on Maple) ? * anyone interested for such developments will express a specific list of desiderata (control, maths,...). How to organize the project so as to provide anyone with the routines he needs ? * What do you think of this ? Does there exist any such project ? I am working under Matlab, that's why this proprietary software is mentionned here. Regards, Hervé Tanguy Hervé Tanguy R&D Engineer SIREHNA PhD Student IRCCyN www.sirehna.com www.irccyn.ec-nantes.fr
