The current CDF and RDF vectors implement fft using GSL. I'm in the process of switching the RDF/CDF vector backend to numpy, and then the fft will be done by numpy. I'm curious where the FFT is done by numpy currently; I couldn't find the code. Of course, the reviewer used an extremely old version of Sage (on our timescale), so maybe things were different then. For matrices, switching to numpy made most things faster, so I'm curious what we'll find when we switch the vectors to numpy as a backend.
