Most Wise Monks,
I am an ex-graduate student (and poor college professor who is temporarily replacing other faculty whilst still having to process data and write papers) who is looking for a cheap (i.e., free) replacement for Matlab and graphing software such as Sigmaplot. I was wondering whether Perl or Python with Numerical Python and SciPy are good replacements for these two software packages, and how one would implement these.
Happy New Year,
Dr. Guy
