[Numpy-discussion] FFTW bindings now implement numpy.fft interface
Sun Feb 17 09:58:39 CST 2013
Some of you may be interested in the latest release of my FFTW bindings.
It can now serve as a drop in replacement* for numpy.fft and
This means you can get most of the speed-up of FFTW with a one line code
change or monkey patch existing libraries.
Lots of other goodness too of course.

It's GPL3 due to license restrictions on FFTW. Get in touch if you want
a different license and I'm sure we can reach an agreement ;)
*In the case where the input array is not a numpy array, it doesn't
work. This was an oversight and will be fixed in the next release. That
said, if you're converting from a list on every transform, you have
better optimisations than using FFTW. One other small caveat in a corner
case to do with repeated axes - described in the docs.
