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.... for example 'exi octave' reveals: * sci-mathematics/koctave Available versions: 0.65-r1 Homepage: http://athlone.ath.cx/~matti/kde/koctave/ Description: A KDE GUI for Octave numerical computing system * sci-mathematics/octave Available versions: 2.1.57-r1 2.1.69 ~2.1.71-r2 ~2.1.72 2.1.73 ~2.1.73-r1 ~2.1.73-r2 Homepage: http://www.octave.org/ Description: GNU Octave is a high-level language (MatLab compatible) intended for numerical computations * sci-mathematics/octave-forge Available versions: ~2004.11.16-r1 2004.11.16-r2 ~2005.06.13 ~2005.06.13-r1 ~2006.01.28 2006.03.17 ~2006.03.17-r1 Homepage: http://octave.sourceforge.net/ Description: A collection of custom scripts, functions and extensions for GNU Octave hth, James -- gentoo-user@g.o mailing list
