[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
