Webnorm{“backward”, “ortho”, “forward”}, optional Normalization mode (see fft ). Default is “backward”. overwrite_xbool, optional If True, the contents of x can be destroyed; the default is False. See fft for more details. workersint, optional Maximum number of workers to use for parallel computation. Web"ortho" - normalize by 1/sqrt(n) (making the IFFT orthonormal) Calling the forward transform (fft()) with the same normalization mode will apply an overall normalization of 1/n between the two transforms. This is required to make ifft() the exact inverse. Default is "backward" (normalize by 1/n). Keyword Arguments:
