Using the Editor and Debugger with Classes
Referring to Class Files
Define classes in M-files just like scripts and functions. To use the editor or debugger with a class file, use the full class name. For example, suppose the file for a class, myclass.m is in the following location: Read More
Understanding Code Analyzer Warnings
Syntax Warnings and Property Names
The MATLAB code analyzer helps you optimize your code and avoid syntax errors while you write code. It is useful to understand some of the rules that the Code Analyzer applies in its analysis of class definition code. This understanding helps you avoid situations in which MATLAB allows code that is undesirable. Read More
Modifying and Reloading Classes
Ensuring MATLAB Uses Your Changes
There is only one class definition for a given class in MATLAB at any given time. When you create an instance of a class, MATLAB loads the class definition. So as long as instances of that class exist, MATLAB does not reload the class definition. Read More

Example of Class Definition Syntax
Example of Class Definition Syntax
The following code shows the syntax of a typical class definition. This example is not a functioning class because it references functions that it does not implement. The purpose of this section is to illustrate various syntactic constructions. Read More
Calling Superclass Methods on Subclass Objects
Calling a Superclass Constructor
If you create a subclass object, MATLAB calls the superclass constructor to initialize the superclass part of the subclass object. By default, MATLAB calls the superclass constructor without arguments. If you want the superclass constructor called with specific arguments, explicitly call the superclass constructor from the subclass constructor. The call to the superclass constructor must come before any other references to the object. Read More

Matlab Events and Listeners
Specifying Events
To define an event, you declare a name for the event in the events block. Then one of the class methods triggers the event using the notify method, which is method inherited from the handle class. Only classes derived from the handle class can define events. Read More
