WebВсякий раз, когда я рисую значения, полученные программой с помощью cuFFT, и сравниваю результаты с результатами Matlab, я получаю ту же форму графиков, а значения максимумов и минимумов получаются в одних и тех же точках. WebcufftPlan1d( cufftHandle *plan, int nx, cufftType type, int batch ); creates a 1D FFT plan configuration for a specified signal size and data type. The batch input parameter tells CUFFT how many 1D transforms to configure. Input plan Pointer to a cufftHandle object nx The transform size (e.g., 256 for a 256-point FFT) type The transform data type (e.g., …

WebOct 19, 2015 · fails with CUFFT_INVALID_VALUE when compiled and run with the CUFFT shipped in CUDA 6.5, but succeeds when built and run against the CUFFT version in CUDA 7.0. As noted in comments, cufftGetSize appears to work correctly in CUDA 6.5. So the workaround is to use cufftGetSize or upgrade to a newer than CUDA 6.5 version of CUFFT.

This is only the case in one axis of a 2D FFT though. You can think of a 2D FFT as two 1D FFT operations, the first operates on all the rows, and for a real valued image this will give you complex row values. termini h busWebJun 15, 2024 · Can anyone tell me how to place a cufftHandle variable inside a C struct such that it can be validly accessed from different C files?
