How do we do it?

 

Once you have opened the GUIDE tool, draw the GUI as you prefer using Drag & Drop from the Control Menu to include a new control.

 

Each control has a set of properties that you may change by double-clicking on it. Some of the properties include the Size, Position, Color, Text, and Tag.

 

Once you saved the GUI, MATLAB will open the associated .m file. There you will see a Callback method associated to each control you created. To understand a little bit more about callbacks, you can refer to:
