Getting Started

LTI Viewer

The LTI Viewer is a GUI for viewing and manipulating the response plots of linear models. You can display the following plot types for linear models using the LTI Viewer:

• Step and impulse responses
• Bode and Nyquist plots
• Nichols plots
• Singular values of the frequency response
• Pole/zero plots
• Response to a general input signal
• Unforced response starting from given initial states (only for state-space models)

Note that time responses and pole/zero plots are available only for transfer function, state-space, and zero/pole/gain models.

Note    The LTI Viewer displays up to six different plot types simultaneously. You can also analyze the response plots of several linear models at once.

This figure shows an LTI Viewer with two response plots.

The LTI Viewer with Step and Impulse Response Plots

The next section presents an example that shows you how to import a system into the LTI Viewer and how to customize the viewer to fit your requirements.
