# Extract Output Elements of Feedback System

This example demonstrates how to extract the output elements of a state-space system that uses vector signals.

Open the example model.

These equations define the state-space system:

To ensure that the system is stable, the state feedback vector is chosen such that the eigenvalues of equal , , , and .

The Demux block extracts the two elements from the output vector . Then, the Scope block separately plots each element it receives.
