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:

  

• Column-wise multiplication if major = VSIP_COL:

  

for all from 0 to and from 0 to , where is the number of rows and 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.
