C2000 IQN x IQN

Multiply IQ numbers with same Q format

Description

This block multiplies two IQ numbers. Optionally, it can also round and saturate the result.

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.
