thanks for your comments. If I got you right, I should look for a
FFT-code that uses SSE (what does this actually stand for?), which means
that it vectorizes 32bit-single-operations into larger chunks that make
efficient use of recent CPUs.
You mentioned FFTW and MKL. Is this www.fftw.org and the 'intel math
kernel library'? If I would like to use one of them, is numpy the right
place to put it in?
Does anyone know, if it is possible to switch on SSE support (at compile
time) in the fftpack.c that numpy uses?
