What Is a GUI?

A graphical user interface (G UI) is a graphical display in one or more

windows containing controls, called components, that enable a user to perform

interactive tasks. The user of the G UI does not have to create a script or

type commands at the command line to accom plish the tasks. Unlike coding

programs to accomplish tasks, the user of a GUI need not understand the

details of how the tasks are performed.

GUI components can include menus, toolbars, push buttons, radio buttons,

list boxes, and sliders—just to name a few. GUIs created using MATLA B

tools can also perform any type of computation, read and write data files,

communicate with other GUIs, and display data as tables or as plots.

The following figure illustrates a simple GUI that you can e asily build

yourself.
