                vsip_cscalar_f alpha, vsip_cvview_f const *r); 
void vsip_cvmsa_d(vsip_cvview_d const *a, vsip_cvview_d const *b, 
                 vsip_cscalar_d alpha, vsip_cvview_d const *r);

Description

This function performs an element-wise multiply-scalar-add operation on two input vectors and a scalar constant. The operation performs element-wise computation:

ri= (ai·bi)+α

for all $i$ from 0 to $n-1$ , where $n$ is the length of the vectors.

Parameters

vsip_dvview_p const* a: First input vector.
vsip_dvview_p const* b: Second input vector.
vsip_dscalar_p alpha: Scalar argument $α$
vsip_dvview_p const* r: Output vector that will store the results.
