V*n ( x alpha -- x*alpha )
Basic Linear Algebra Subroutines (BLAS) interface » BLAS interface vector operations

Prev:	n*V ( alpha x -- alpha*x )
Next:	V/n ( x alpha -- x/alpha )

Vocabulary
math.blas.vectors

Inputs

x	a blas-vector-base
alpha	a number

Outputs

x*alpha

a blas-vector-base

Word description
Calculate the scalar-vector product αx and return a freshly-allocated vector with the same length as x containing the result. Corresponds to the xSCAL routines in BLAS.
