WebApr 6, 2024 · With cufftPlanMany() function in cuFFT I can set the istride/ostride and idist/odist arguments to accomplish this. I can also set the type to R2C, C2R, C2C (and other datatype equivalents). I appreciate that cupyx.scipy.fftpack.get_fft_plan gives me the ability to set a plan prior to running multiple FFTs.
