BLAS Level 1: rscal

rscal (defined in namespace flens::blas) computes \(y \leftarrow \frac{1}{\alpha} y\) for a vector \(y\).

We also provide a variant that does the computation for matrices instead of vectors.

Vector Variant

alpha	`(input) real scalar` Reciprocal scaling factor for the values in \(y\).
y	`(input/output) real or complex valued DenseVector` On entry the original vector \(y\). On exit overwritten with \(\frac{1}{\alpha}\,y\).

alpha	`(input) real scalar` Reciprocal scaling factor for the values in \(y\).
B	`(input/output) real or complex valued GeMatrix` On entry the original matrix \(B\). On exit overwritten with \(\frac{1}{\alpha}\,B\).
