Ah, that makes sense.
In order to switch to the scipy version, the speed improvement has to
also take into account the fact that I have to recast the result into
the numpy form then.
Right now, my scipy takes twice as long as it is. How do I make sure
it's using fftw3, and is there a way to make numpy use this library?
