Analyzing MIMO Models
In analysis plots of multiple-input, multiple output LTI models, there are plot tools for selecting subsystems and grouping I/O pairs.
Customize Response Plots Using the Response Plots Property Editor
Set axes labels and limits, fonts, grids, and other attributes of response plots.
Toolbox Preferences Editor
Set plot preferences that persist from session to session.
