mot563_abs (Motorola DSP Developer's Kit)

Output the absolute value of the input.

MATLAB Syntax

Y=mot563_abs(X)

Description

The mot563_abs function computes the absolute value of the input. When X is complex, mot563_abs(X) is the complex modulus (magnitude) of the elements of X.

Characteristics

In the workspace, if the input is:

X=[0.9501+0.2311j    0.6068-0.4860j]

Y=mot563_abs(X,'56301')

the answer returned by the function is:

Y=[0.9778    0.7774]

Arguments
X
Vector (or matrix) with elements normalized in the range [-1,1] (for complex elements, both real and imaginary parts should comply with this limit).

Y
Output vector in range [0, 1.414].
