BLAS Level 1: scal

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

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

Vector Variant

Defined in namespace flens::blas. Function scal with 2 template parameters.

alpha	`(input) real scalar` 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 \(\alpha\,y\).

alpha	`(input) real scalar` 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 \(\alpha\,B\).
