Create the Simple Programmatic GUI Code File

Start by creating a file for the example GUI. Because the file will contain

functions, it is a function file as opposed to a script file, which contains a

sequence of MATLAB commands but does not define functions.

1 At the MATLAB prompt, type edit. M ATLAB opens a blank do cument in

the Editor.

2 Type or copy the following statement into the editor. This funct ion

statement is the first line in the file.

function si

mple_gui2

3 Type or paste these comments into the file following the function statement.

They display at the command line in response to the

help command. Follow

them by a blank line, which MATLAB requires to terminate the help text.

% SIMPLE_

GUI2 Select a data set from the pop-up menu, then

% click on

e of the plot-type push butt ons. Clicking the b utton

% plots th

e selected data in the axes.

(Leave a

blank line here)

4 Add an end statement at the end of the file. This end statement matches

the

function statement. Your file now looks like this.

functi

on simple_gui 2

% SIMPL

E_GUI2 Select a data set fr om the pop-up menu, then

%clic

k one of the plot-type push buttons. Clicking the button

%plot

s the selected data in the axes.

end

Note You need the end statement because the example is written using

nested functions. To learn more, see “Nested Functions”.

5 Save the file in your current folder o r at a location that is on your MAT LAB

path.
