Welcome to pyFFTW’s documentation!¶
pyFFTW is a pythonic wrapper around FFTW, the speedy FFT library. The ultimate aim is to present a unified interface for all the possible transforms that FFTW can perform.
Both the complex DFT and the real DFT are supported, as well as on arbitrary
axes of abitrary shaped and strided arrays, which makes it almost
feature equivalent to standard and real FFT functions of
(indeed, it supports the
clongdouble dtype which
numpy.fft does not).
Operating FFTW in multithreaded mode is supported.
The core interface is provided by a unified class,
This core interface can be accessed directly, or through a series of helper
functions, provided by the
pyfftw.builders module. These helper
functions provide an interface similar to
numpy.fft for ease of use.
In addition to using
pyfftw.FFTW, a convenient series of functions
are included through
pyfftw.interfaces that make using
almost equivalent to
The source can be found in github and its page in the python package index is here.
A comprehensive unittest suite is included with the source on the repository. If any aspect of this library is not covered by the test suite, that is a bug (please report it!).
