The documentation for scipy.signal.resample says that it assumes the function is periodic. Is interp1d the equivalent function for nonperiodic signals? If not, what is?

I've spent a lot of time searching for this and reading through other posts, but they all seem to assume you have a signal processing background; I'm from more of an algorithms background. I kind of understand what "Fourier methods" are, but shouldn't there be some kind of Fourier-based resampler for finite-length signals? (Perhaps using a DFT, etc.)

    From your description of the problem, I think `interp1d` is likely what you want. It's hard to be definitive without example data and a more thorough description of what you're trying to achieve. – Frodnar Apr 27 '21 at 16:34
