np.fft.rfft for spectral derivatives in Python

For real-valued inputs, the rfft saves about half of the computation over the classical fast Fourier transform. Let's use it to speed up the spectral derivative calculation. Here is the code: https://github.com/Ceyron/machine-learning-and-simulation/blob/main/english/fft_and_spectral_methods/spectral_derivative_numpy_with_rfft.ipynb ------ 👉 ...
