Efficient and easy Fast Fourier Transform for Python.
This package provides C++ classes and their Python wrapper classes written in Cython useful to perform Fast Fourier Transform (FFT) with different libraries, in particular
Fluidfft provides an uniform API for all these libraries. Fluidfft can be used for example as a base to write pseudo-spectral simulation codes. In particular, fluidfft is used in the code fluidsim. Fluidfft also provides classes to efficiently perform linear operators (gradient, divergence, rotational, etc.) and easily deal with the data distribution (gather the data on one process, scatter the data to many processes).
