[SciPy-dev] Cleaning and fixing fft in scipy ?
Fri Apr 27 05:43:52 CDT 2007
When fixing the fft problem with prime number in numpy, I came again
across the fft implementation in scipy, and related problems (suboptimal
solution for fftw, see eg scipy ticket #1). I would like to improve the
- First, I think the module needs serious cleaning, as for now, it
is a bunch of C files with many #define all accross the code, making it
difficult to track things. I propose to split the sources by
implementation (fft_fftw3.c, fft_fft2, fft_mkl, etc...); this can be
done without any consequence on the implementation.
- Then, improving fft where it is needed.
Does this sound ok with scipy developers ?
I should come up with a patch for zfft within today; even if I try
to keep changes minimal, I would need people willing to test (I can
easily test on linux with fftw2 and 3, and if necessary with mkl on the
same platform. I would prefer avoiding testing on windows myself, as I
have only a Japanese windows, making things extremely painful for me on
this already painful platform).
