Programming the GUI M-file
After laying out your GUI, you can program the GUI M-file using the M-file
editor. GUIDE automatically generates this file from your layout the first time
you save or run the GUI. The GUI M-file
• Initializes the GUI
• Contains code to perform tasks before the GUI appears on the screen, such
as creating data or graphics
• Contains the callback functions that are executed each time a user clicks a
GUI component
Initially, each callback contains just a function definition line. You then use the
M-file editor to add code that makes the component function the way you want
it to. To open the M-file, click the M-file Editor icon on the Layout Editor
toolbar. The following figure shows the M-file for the GUI with Axes and Menu
template.
