Here is some Matlab code to demonstrate the FFT of a non-periodic square pulse. Timing.m ( it can be called by issuing command “timing(2048, 4)” as an example ) function = timing(datasize, batch)ĭisp('CUFFT: ') tic a = mexCUFFT(d) toc ĭisp('MATLAB FFT: ') tic b = fft(d) toc The fft function in MATLAB uses a fast Fourier transform algorithm to compute the Fourier transform of data. It looks like the original question is several years old, but there is a recent reply. So can anyone point how i can get speedup of maybe 10x in fft code just as mentioned in the white paper in this page? Thanks in advance! Currently when i call the function timing(2048*2048, 6), my output is CUFFT: Now i’m having problem in observing speedup caused by cuda.

The matlab code and the simple cuda code i use to get the timing are pasted below. Hi all, I’ve got my cuda (FX Quadro 1700) running in Fedora 8, and now i’m trying to get some evidence of speed up by comparing it with the fft of matlab.
