# vectorOps

Perform vector and matrix BLAS functions on arrays of 128-bit vectors.

## Overview

Overview vectorOps.h declares a set of vector and matrix BLAS functions on arrays of 128-bit vectors containing single-precision floating-point values. The arrays can be of any desired length, but the number of float elements must be a multiple of 4.
