# 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.

## Basic Examples(1)

Scale a vector by a scalar:

## Scope(4)

A real vector:

A complex vector:

An arbitrary-precision vector:

A symbolic vector:

## Properties & Relations(1)

SCAL[α,x] is equivalent to x=α x:

## Possible Issues(2)

The second argument must be a symbol:

If the second argument is not initialized, an error message is issued:
