Function std::rocm_fft_c2r

#include <std/dsp/fft_rocm.h> source ยท definition

int rocm_fft_c2r(
    struct RocmBuf in,
    struct RocmBuf out,
    unsigned long n,
    unsigned long batch,
)

batch x (n/2 + 1) complex -> batch x n real. May overwrite 'in' (rocFFT's complex-to-real transforms use their input as scratch).
