WebJul 17, 2014 · plan = cufftPlan1d (&plan, n, CUFFT_D2Z, 1); The function itself sets the plan (that is why you pass &plan to the function), then when you assign the return value into the plan, it ruins the plan set up by the function. You correctly identified that the output can be of size ( (N/2)+1), but then you didn't allocate space for it properly either ... WebMay 24, 2011 · cufftHandle abc; cufftResult res1=cufftPlan1d(&abc, 128, CUFFT_Z2Z, 1); and in “res1” I have still error 0x4: CUFFT_INVALID_VALUE. I tried to run my application on various types of CUDA hardware, on winxp64 and Windows 7x64. I tried to run only mexw64 library with matlab and also winapi in VS2010. I used cufft 3.2 and 4.0 (for x64 system).
