I have MatLab code that was converted to Fortran (f90). I have used FFTW libraries for my FFT replacement. However, my numerical results are not identical to what comes out of MatLab and the original f90 code, which used a much slower FFT. I am looking for someone to do some testing of my current codes, under gfortran / g++, which I have implemented under MSYS/MinGW-64 bit. I want to testing to be done under the identical set-up: FFTW installed under MSYS/MinGW-64 bit using gfortran/g++. The idea would be to test against the original MatLab code, and try to find any bugs that may have crept in during the conversion from MatLab to f90 and using FFTW. Must be able to communicate in english, and must be familiar with: MatLab, F90. FFTW experience a plus, but must have FFTW running under MSYS/MinGW-64 before accepting the project.

I am familiar with both matlab and Fortran. And uses fftw in my own research, I may have a try of you code, and only get paid if I can solve you problem

hello, not a real bid, since i have no time to do it over MinGW, but i wonder how the accuracy goes with gfortran/g++ in its native Linux environment. that i could check. perhaps it'll provide a clue where the focus should be put. greets, srdjan

Hello, I have some experience with Matlab and Fortran, but I haven't used neither of these for a long time. If you don't find anyone to help you with this project, please contact me. I can install FFTW and MSYS/MinGW-64 and test it for you.

Your problem sounds intriguing. I have MatLab and MSYS/MinGW (I think 32-bit though) with gfortran already installed. I don't have the FFTW libraries but I can download them.

I have much experience with matlab, fortran and fft (also fftw) due to my research interest. Coding and debugging is a common task for me in various environments. Using minGW-64 is no problem for me.
