BLAS Level 1 Extension: raxpy
raxpy (defined in namespace flens::blas) computes \(y \leftarrow y +\frac{1}{\alpha} x\) where \(x, y\) are vectors and \(\alpha\) is a constant scalar. raxpy is short for reciprocal of alpha times x plus y.
We also provide a variant that does the computation for matrices instead of vectors.
