WebOperating FFTW in multithreaded mode is supported. The core interface is provided by a unified class, pyfftw.FFTW . 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. WebPython 3.4 support has been dropped. pyFFTW now supports Python 2.7 and 3.5-3.8. The Cython code has been updated to explicitly use language_level=3str for compatibility with a future Cython 3.0 release. Authors Peter Bell + Gregory R. Lee Stefan Peterson + DWesl + A total of 4 people contributed PRs to this release.
