Cufft plan

WebFrees all GPU resources associated with a cuFFT plan and destroys the internal plan data structure. This function should be called once a plan is no longer needed, to avoid wasting GPU memory. Parameters: plan[In] – The cufftHandle object of the plan to be destroyed. Return values: CUFFT_SUCCESS – cuFFT successfully destroyed the FFT plan ...
