Basic LTI Viewer Tasks
LTI Viewer is a graphical user interface (GUI) that simplifies the analysis of linear, time-invariant systems. You use the LTI Viewer to view and compare the response plots of SISO and MIMO systems, or of several linear models at the same time. You can generate time and frequency response plots to inspect key response parameters, such as rise time, maximum overshoot, and stability margins.
The easiest way to work with the LTI Viewer is to use the right-click menus. For example, type
at the MATLAB prompt. The default plot is a step response.

The LTI Viewer can display up to seven different plot types simultaneously, including step, impulse, Bode (magnitude and phase or magnitude only), Nyquist, Nichols, sigma, pole/zero, and I/O pole/zero.
See ltiview for help on the function that opens an LTI Viewer. For examples of how to use the LTI Viewer, see Analyzing Models in Getting Started with the Control System Toolbox.
