 Jan19 awarded Teacher Jan7 comment Need numerical approximation for Fourier{max(0,f(x,y))} given Fourier{f(x,y)} thank you, It does seem like there is no easy trick to actually gain computation time here. If by chance you know any example for a non linear operartion that does have some specific trick, I would love to hear about it. Jan7 awarded Supporter Jan7 comment Need numerical approximation for Fourier{max(0,f(x,y))} given Fourier{f(x,y)} @PavelM, thank you for pointing out the error, it seems I am lacking some theoretical background, do you have a good source on non linear transforms?
