function plp_rfftfast_f32
void plp_rfftfast_f32(
const plp_fft_fast_instance_f32 * S,
const float32_t *__restrict__ pSrc,
float32_t *__restrict__ pDst
)
Floating-point FFT on real input data.
Parameters:
- S points to an instance of the floating-point FFT structure
- pSrc points to the input buffer (real data)
- pDst points to the output buffer (complex data)
Return: none
