matlab/octave, python, r cross reference

===== Original message from Alan G. Isaac | Thu, 28 Jul 2005:

More natural choices might be
- GAUSS - PDL - SciLab - Lush - Yorick - Algae - A+

thanks for the input.
how different are PDL, IDL and GDL?
aren't there a PyDL or pyIDL also?
or is this something different?

this resource might be useful for this, i guess?
