C2000 Absolute IQN

Absolute value

Description

This block computes the absolute value of an IQ number input. The output is also an IQ number.

Note

The implementation of this block does not call the corresponding Texas Instruments^® library function during code generation. The TI function uses a global Q setting and the MathWorks^® code used by this block dynamically adjusts the Q format based on the block input. See Using the IQmath Library for more information.
