File Organization

Typically, a UI code file has the following ordered sections. You can help to maintain the

structure by adding comments that name the sections when you first create them.

1 Comments displayed in response to the MATLAB help command.

2 Initialization tasks such as data creation and any processing that is needed to

construct the components. See “Initialize a Programmatic UI” on page 11-2 for

more information.

3 Construction of figure and components. For more information, see “Create Figures

for Programmatic UIs” on page 10-4 and “Add Components to a Programmatic

UI” on page 10-9.

4 Initialization tasks that require the components to exist, and output return. See

“Initialize a Programmatic UI” on page 11-2 for more information.

5 Callbacks for the components. Callbacks are the routines that execute in response

to user-generated events such as mouse clicks and key strokes. See “Write Callbacks

Using the Programmatic Workflow” on page 11-5 for more information.

6 Utility functions.

File Template

This is a template you can use to create a UI code file:

function varargout = myui(varargin)

% MYUI Brief description of program.

% Comments displayed at the command line in response

% to the help command.

% (Leave a blank line following the help.)
