void vsip_cvsam_f(vsip_cvview_f const *a, vsip_cscalar_f beta, 
                 vsip_cvview_f const *c, vsip_cvview_f const *r); 
void vsip_cvsam_d(vsip_cvview_d const *a, vsip_cscalar_d beta, 
                 vsip_cvview_d const *c, vsip_cvview_d const *r);

Description

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

ri=β(ai+ bi)

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_dscalar_p beta: Scalar constant $β$ .
vsip_dvview_p const* c: Third input vector.
vsip_dvview_p const* r: Output vector that will store the results.
