Setting Preferences

Overview of Setting Preferences

Use File > Preferences to customize displays and certain parameters for SPTool and its four component GUIs. If you change any preferences, a dialog box displays when you close SPTool asking if you want to save those changes. If you click Yes, the new settings are saved on disk and are used when you restart SPTool from the MATLAB® workspace.


You can set MATLAB preferences that affect the Filter Visualization Tool only from within FVTool by selecting File > Preferences. You can set FVTool-specific preferences using Analysis > Analysis Parameters.

When you first select Preferences, the Preferences dialog box opens with Markers selected by default.

Change any marker settings, if desired. To change settings for another category, click its name in the category list to display its settings. Most of the fields are self-explanatory. Details of the Filter Design options are described below.

  • Select colors and markers for all displays.
