Description

This function performs an element-wise multiply-subtract operation on three input vectors. The operation performs element-wise computation:

ri= (ai·bi)-ci

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_dvview_p const* c: Third input vector.
vsip_dvview_p const* r: Output vector that will store the results.
