Hello all, For a project in DIPY (http://dipy.org) we need to be calling 1D and 2D FFTs and iFFTs very often. For this reason the most efficient way seems to be through Cython.
It would be great if we could call scipy's fft or numpy's fft without the overhead. I would like to ask if someone has worked on this and can share some of hers/his experience or code. What we are trying to do is avoid increasing our dependencies. For example we prefer not using FFTW if this is not available in scipy/numpy. Finally, many thanks to scipy devs and cython devs for making available BLAS and LAPACK functions from Cython. This has been super useful for our project. I hope we can do something similar for FFT. Let me know if you have any ideas. Can we for example access the FFT functions of scipy directly from Cython. Has someone done this? Best regards, Eleftherios
