I read:
I have a project where i need to analyse the HR, GSR and Muscular signals, and from that, trigger some PD patches. I need to analyse this data inside PD. I'm thinking of gathering the data into 3 arrays, one for each signal, and with a 2 minute interval, i will analyse the data. Problem is the analysis of the arrays...
probably the most versatile library for nonrealtime array work is thomas' vasp -> http://www.parasitaere-kapazitaeten.net/vasp/ (find VASP-HELP.pd and look in objects -> filters and minmax)
you also might want to look at the array docs in doc/2.control.examples/ since tabread is your friend.
