6.1 System Generator for DSP - What is the purpose of the "z" input to the CORDIC Atan block?

Description

General Description: 

I want to use the CORDIC Arctan block in the System Generator Reference Blockset, which has three inputs: x, y and z. 

 

What is the purpose of the "z" input?

Solution

The "z" input is not required for the Arctan function and has been removed in System Generator v6.2. For the documentation on the latest version of the CORDIC Arctan block, refer to the following:
