Re: [Numpy-discussion] Numpy FFT normalization options issue (addition of new option)

Hello, - my first reaction would be that the less argument names we change at a time the better, so that we don't confuse people or cause codes written with previous NumPy versions to break. Personally I always think of "ortho" as "orthonormal", which immediately brings "unit norm" to mind, but I

[Numpy-discussion] Add Chebyshev (cosine) transforms implemented via FFTs

2020-08-03 Thread Chris Vavaliaris
PR #16999: https://github.com/numpy/numpy/pull/16999 Hello all, this PR adds the two 1D Chebyshev transform functions `chebyfft` and `ichebyfft` into the `numpy.fft` module, utilizing the real FFTs `rfft` and `irfft`, respectively. As far as I understand, `pockefft` does not support cosine transfo
