It's unclear what you are after. Advice on which
mathematical approaches
will work or which software contains those mathematical
approaches?
Matlab is the standard for mathematical analysis of all
sorts of
phenomenon, from a mathematical perspective.

Very unclear what you are saying. Are these signals related
to events in
your network? More information will help.

You might want to
'cd /usr/portage' and then pick a dir...
'cd sci-mathematics' and emerge some software who's
description
you find potentially interesting....
