I have such a problem - I would need to expand a discrete function in a sine fourier series but I would like to use exponential based library for FFT (I will use CUDA to compute it).What have I to do with the signal I'm sending to the procedure so this is treated as sine fourier? I think I should add zeros but I am not sure where they have to be.Many thanks
