4.3.18 vsip_rvcmmul_p - Real Vector-Complex Matrix Multiplication

void vsip_rvcmmul_f(const vsip_vview_f* a, const vsip_cmview_f* b, 
                   vsip_major major, const vsip_cmview_f* r);

Description

This function performs a real vector-complex matrix multiplication. The operation performs either:

Row-wise multiplication if major = VSIP_ROW:
$ri,j= aj·bi,j$
Column-wise multiplication if major = VSIP_COL:
$ri,j= ai·bi,j$

for all $i$ from 0 to $m -1$ and $j$ from 0 to $n-1$ , where $m$ is the number of rows and $n$ is the number of columns in the matrix.

Parameters

const vsip_vview_p* a: Input real vector containing the multiplier elements.
const vsip_cmview_p* b: Input complex matrix to be multiplied.
vsip_major major: Storage order specifying the multiplication direction:
- VSIP_ROW: Multiply each row of the matrix by the corresponding vector element
- VSIP_COL: Multiply each column of the matrix by the corresponding vector element
const vsip_cmview_p* r: Output complex matrix that will store the results.

Notes

The length of the real vector must match either the number of columns (for VSIP_COL) or the number of rows (for VSIP_ROW) in the complex matrix.
