Hopefully these are mature enough to be generally useful. I would appreciate any comments regarding the interface. The FFTW API is not particularly nice for building a pure interface on.
because FFTW stores global data (called 'plan's)
Some of the transforms could be made slightly faster at the expense of a much nastier interface, but unless someone needs the extra few percent, or is pushing the memory limits on their machine, I'm not inclined to expose the underlying nastiness.
I want to mention once again that there is already a Fast Fourier transform for arbitrary length that is coded entirely in Haskell. http://hackage.haskell.org/packages/archive/dsp/0.2/doc/html/Numeric-Transfo...
