[SciPy-User] [OT] looking for fft
Wed Apr 17 09:08:43 CDT 2013
I'm looking for some fft code that has:
1. commercial-friendly license
2. seperates construction (which involves costly trig functions) from repeated
use (which should use only multiply-add)
An example of (2) is fftw, but that doesn't meet (1).
I've seen plenty of examples that have (1) but not (2) - these use fft as a
function, which has no state. fft should be written as a class, where in the
constructor all the trig functions are determined.
