WebCython at a glance ¶. Cython is a compiler which compiles Python-like code files to C code. Still, ‘’Cython is not a Python to C translator’’. That is, it doesn’t take your full program and “turn it into C” – rather, the result … 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.
