Many thanks! I haven't been able to figure out what is causing the problem in my code but based on yours I've been able to do functions that suit my needs. I've encapsulated the direct (forward) transform in one function and the inverse (backwords) transform in other. In this way I do the...

This is the piece of code that it does not work: ... #include <complex>//Includes C++ complex numbers (uses templates) #include <fftw3.h> // Library to perform FFT transform (GPL license) const int BLOCKSIZE= 10; ... // Applies an MTF to an image. This filters the image. It is...

Thank you Eric, I will have a look to sourceforge. I need to do it in C or C++. The Fourier transform is just a step in a much bigger software we are developing. We already have a prototype in Matlab and I do the Fourier transforms there without any problem.

Does anyone know a good free library to do Fourier Transforms (FFT or DFT). I know FFTW but I'm having some problems with it. I want an alternative that do FFT in two dimensions with complex numbers. The libraries I have found doesn't fulfill this requirements. Thank you
