The code is sequential and the main processing operation in the code is a 2D FFT of 2D images. The current Matlab code is very slow even with the parallel computing option being enabled. ... I need an optimized version of my algorithm, possibly using cuFFT?. More information about the Matlab code: The current Matlab code is highly modular and well written. ... Required libraries HDF5 - https://www.hdfgroup.org/HDF5/ cuFFT - https://developer.nvidia.com/cufft Proposed milestones: Stage 1: read Data from Matlab format (.mat) in to C/C++ and providing the CUDA c++ code for the intermediate operations.

Hi, I had a signal that I used FFT on and the I used IFFT on the signal without changing anything in the FFT but I still didn't get my time domain plot back! ... I want to to know what the problem is and fix it. Y = fft(A); B = ifft(Y,'symmetric'); and B that I get is not equal to A so why is that?
