Functions Documentation

function plp_cmplx_mult_cmplx_f32

void plp_cmplx_mult_cmplx_f32(
    const float32_t *__restrict__ pSrcA,
    const float32_t *__restrict__ pSrcB,
    float32_t *__restrict__ pDst,
    uint32_t numSamples
)

Floating-point complex-by-complex multiplication.

Parameters:

  • pSrcA points to first input vector
  • pSrcB points to second input vector
  • pDst points to output vector
  • numSamples number of samples in each vector

Return: none
