pyNFFT3 Documentation¶
pyNFFT3 is a Python interface for the NFFT library using ctypes.
pyNFFT3 currently provides the following fast algorithms:
nonequispaced fast Fourier transform (NFFT)
nonequispaced fast cosine transform (NFCT)
nonequispaced fast sine transform (NFST)
nonequispaced fast spherical Fourier transforms (NFSFT)
fast spherical Fourier transforms (FSFT)
fast summation (fastsum)
