| July 7, 2009 11:38 AM PDT Using FFTW Wrapper - fftw_plan_many_dft | ||||
I was hoping someone could shed some light... I have inherited an application which originally uses FFTW and has been compiled to work with MKL. There are calls to fftw_plan_many_dft, and I am having difficultly on what is actually being calculated. The call is the following: fftw_plan_many_dft(rank, *n, howmany, inembed, istride, idist, onembed, ostride, odist, sign) rank = 1 (1D FFT) *n = n[0] = 4096 howmany = 64 inembed = onembed = NULL (default to n[0]) istride = ostride = 64 idist = odist = 1 sign = 1 or -1 (INVERSE or FORWARD) What confuses me is the stride != 1, any help would be greatly appreciated. | |||||
