WebAs the title states I'm using FFTW (version 3.2.2) with Fortran 90/95 to perform a 2D FFT of real data (actually a field of random numbers). I think the forward step is working (at least I am getting some ouput). However I wanted to check everything by doing the IFFT to see if I can re-construct the original input.

WebJul 11, 2024 · FFTW vs fourn subroutine result does not match. I'm converting/rewriting a old Fortran codebase to modern one. One of the segment of the code base uses fourn subroutine (from the Numerical receipies book) for FFT purpose. But when I'm trying to do that exact thing with the FFTW library it does not produce same result. I'm confused here. http://sep.stanford.edu/sep/claudio/Research/Prst_ExpRefl/ShtPSPI/intel/mkl/10.0.3.020/doc/fftw2xmkl_notes.htm

WebFor example, instead of calling the C wrapper fftw_one, in Fortran, you should call the fftw_f77_one wrapper. FFTW Fortran functions are actually the wrappers to FFTW C functions. Fortran wrappers are actually the wrappers to C wrappers. So their functionality and argument restrictions are the same as of the corresponding C wrappers.
