7 It's unclear what you are after. Advice on which mathematical approaches
8 will work or which software contains those mathematical approaches?

10 Matlab is the standard for mathematical analysis of all sorts of
11 phenomenon, from a mathematical perspective.

33 'cd sci-mathematics' and emerge some software who's description
