[Numpy-discussion] fourier with single precision

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?
