sigmaoptions - Create list of singular-value plot options

Syntax

P = sigmaoptions P = sigmaoptions('cstprefs')

Description

P = sigmaoptions returns a list of available options for singular value plots with default values set. You can use these options to customize the singular value plot appearance from the command line.

P = sigmaoptions('cstprefs') initializes the plot options you selected in the Control System Toolbox Preferences Editor. For more information about the editor, see Toolbox Preferences Editor in the User's Guide documentation.

This table summarizes the sigma plot options.

Option	Description
Title, XLabel, YLabel	Label text and style
TickLabel	Tick label style
Grid [off\|on]	Show or hide the grid
XlimMode, YlimMode	Limit modes
Xlim, Ylim	Axes limits
IOGrouping [none\|inputs\|output\|all]	Grouping of input-output pairs
InputLabels, OutputLabels	Input and output label styles
InputVisible, OutputVisible	Visibility of input and output channels
FreqUnits [Hz\|rad/s]	Frequency units
FreqScale [linear\|log]	Frequency scale
MagUnits [dB\|abs]	Magnitude units
MagScale [linear\|log]	Magnitude scale

Examples

In this example, set the frequency units to Hz before creating a plot.

P = sigmaoptions; % Set the frequency units to Hz in options 
P.FreqUnits = 'Hz'; % Create plot with the options specified by P
h = sigmaplot(rss(2,2,3),P);

The following singular value plot is created with the frequency units in Hz.
