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

Prev:	Vamax ( x -- max )
Next:	n*V ( alpha x -- alpha*x )

Vocabulary
math.blas.vectors

Inputs and outputs

alpha	a number
x	a blas-vector-base
x=alpha*x	a blas-vector-base

Word description
Calculate the scalar-vector product αx and replace the existing contents of x with the result. Corresponds to the xSCAL routines in BLAS.

Side effects
Modifies x
