The following piece of code gives an error message 'Compiled expression should be a rank 1 tensor of machine-size complex numbers' Compile[{{m, _Real, 2}}, Fourier[m]][Table[N[i - j], {i, 4}, {j, 4}]] Does this mean that Fourier[] cannot be compiled with rank 2 arrays? My goal is to write a pseudospectral code to solve 2D PDE: compiling the time loop seems unavoidable if one wants reasonable performance. Thanks. Alberto Verga. Alberto.Verga at irphe.univ-mrs.fr
