SCAL

SCAL[α,x]

computes the scaled vector α x and resets x to the result.

Details and Options

To use SCAL, you first need to load the BLAS Package using Needs["LinearAlgebra`BLAS`"].
The following arguments must be given:
α input expression scalar multiple

x input/output symbol vector; the symbol value is modified in place
SCAL[α,x] is equivalent to x=α x.
