Tool and Viewer Reference

Edit

Note    Click on any of the items listed in the Edit menu pictured below to get help contents.

The Edit menu contains the following options:

• Plot Configurations -- Opens the Plot Configurations window
• Refresh Systems -- Updates imported systems
• Delete opens the LTI Viewer Delete window
• Line Styles -- Opens the Line Styles editor
• Viewer Preferences -- Opens the Viewer Preferences editor

Plot Configurations Window -- Selecting Response Types

Plot Configuration under the Edit menu opens the Plot Configurations window.

Use this window to select the number and kind of response plots you want in a single instance of the LTI Viewer. You can plot up to six response plots in a single viewer. Click the radio button to the upper left of the configuration you want the viewer to use.

You can select among eight response types for each plot in the viewer. These are the available response types:

• Step
• Impulse
• Bode -- Plots the Bode magnitude and phase
• Bode mag. -- Plots the Bode magnitude only
• Nyquist
• Nichols
• Singular Values
• Pole/Zero map
• I/O pole/zero map

Refresh Systems

Refresh updates imported models to reflect any changes made in the MATLAB workspace since you imported them.

Delete Systems

Delete under Systems in the Edit menu opens the LTI Viewer Delete window

To delete a model

• Click on the desired model in the Model ist. To perform multiple selections:
1. Click and drag over several variables in the list.
2. Hold the Control key and click on individual variables.
3. Hold the Shift key while clicking, to select a range.
• Click the OK or Apply Button

Line Styles Editor

Select Line Styles under the Edit menu to open the Line Styles editor.

The Line Styles editor is particularly useful when you have multiple systems imported. You can use it change line colors, add and rearrange markers, and alter line styes (solid, dashed, and so on).

The Linestyle Preferences window allows you to customize the appearance of the response plots by specifying:

• The line property used to distinguish different systems, inputs, or outputs
• The order in which these line properties are applied

Each LTI Viewer has its own Linestyle Preferences window.

Setting Preferences.   You can use the "Distinguish by" matrix to specify the line property that will vary throughout the response plots. You can group multiple plot curves by systems, inputs, outputs, or channels (individual input/output relationships). Note that the Line Styles editor uses radio buttons, which means that you can only assign one property setting for each grouping (system, input, etc.).

Ordering Properties.   The Order field allows you to change the default property order used when applying the different line properties. You can reorder the colors, markers, and linestyles (e.g., solid or dashed).

To change any of the property orders, click the up or down arrow button to the left of the associated property list to move the selected property up or down in the list

Viewer Preferences

Viewer Preferences opens the LTI Viewer Preferences editor, which you can use to set response plot defaults for the LTI Viewer that is currently open.

For a complete description of the LTI Viewer Preference editor, as well as all the property and preference editors available in the Control System Toolbox, see Customization in the online Control System Toolbox documentation. To go directly to the LTI Viewer Preferences editor documentation, see LTI Viewer Preferences in the same document.

Window

Use the Window menu to select which of your MATLAB windows is active. This menu lists any window associated with MATLAB and the Control System Toolbox. The MATLAB Command Window is always listed first.
