Or January MerriLUG where I am presenting on Python.

Do you know if Python (scientific/scipy) is available

This document suggests that CorePy can interface to numpy:

and this page shows using yum to install numpy on a PS3 running FC6 so I

Python is *much* higher-level than C! However one area where Python is

you should be aware of that.

scipy apparently will use fftw if it is available:
