Creating Graphical User Interfaces

GUI Allows Only One Instance to Run (Singleton)

This option allows you to select between two behaviors for the GUI figure:

• Allow MATLAB to display only one instance of the GUI at a time.
• Allow MATLAB to display multiple instances of the GUI.

If you allow only one instance, MATLAB reuses the existing GUI figure whenever the command to run the GUI is issued. If a GUI already exists, MATLAB brings it to the foreground rather than creating a new figure.

If you clear this option, MATLAB creates a new GUI figure whenever you issue the command to run the GUI.
