And this change in size has ramifications for data arrangement. Specifically, the sizeof the input buffer is R* (C/2 + 1)*sizeof (cufftComplex). For the R=4, C=4 example case, that is 12*sizeof (cufftComplex) or 24*sizeof (cufftReal), but it is still ...
WebВы меняете ряды столбцами в плане манжеты? Прототипом является cufftPlan2d(cufftHandle *plan, int nx, int ny, cufftType type), где nx - количество строк, а ny - количество столбцов, поэтому должно быть cufftPlan2d(&fwplanA, H, W, CUFFT_R2C);, а не cufftPlan2d(&fwplanA, W, H, CUFFT_R2C);.
