The GUI Files

By default, GUIDE stores a GUI in two files which are generated the first time

you save or run the GUI:

• A FIG-file, with extension

.fig, that contains a complete description of the

GUI layout and the GUI components, such as push buttons, axes, panels,

menus, and so on. The FIG-file is a binary file and you cannot modify it

except by changing the layout in GUIDE. Note that a FIG-file is a kind of

MAT-file. See MAT-Files for more information.

• An M-file, with extension .m, that contains the code that controls the GUI,

including the callbacks for its components.

These two files usually reside in the same directory. They correspond to the

tasks of laying out and programming the GUI. When you lay out the GUI in the

Layout Editor, your work is stored in the FIG-file. When you program the GUI,

your work is stored in the corresponding M-file.

Note that if your GUI includes ActiveX components, GUIDE also generates a

file for each ActiveX component. See “ActiveX Control” on page 8-31 for more

information.

Note You can choose to save only the FIG-file for a GUI. See “Saving and

Displaying Only the GUI Layout” on page 7-12

For more information about these files, see “GUI Files: An Overview” on

page 8-5.
