子类应用程序

将内置类归为子类并定义接口

从内置类派生类，以定义扩展可对特定数据类执行的操作的专用数据类型。子类会继承内置类的方法及行为，并且可以添加新方法以执行专门的操作。

主题

异构类层次结构

A Class Hierarchy for Heterogeneous Arrays
Heterogeneous class hierarchies enable you to form arrays of different, but related classes.

内置类型的子类

Subclasses of MATLAB Built-In Types
Extend MATLAB^® built-in classes by deriving from these fundamental data types.
Behavior of Inherited Built-In Methods
Subclass built-in classes to extend the behavior of functions that operate on that type of data.
Use of size and numel with Classes
The size and numel functions work with user-defined classes.

从内置类派生的示例类

Subclasses of Built-In Types Without Properties
Class can derive from a built-in class without defining properties and new behaviors.
Subclasses of Built-In Types with Properties
Classes that derive from built-in classes and define properties must define array behaviors for those classes.
Enumerations Derived from Built-In Classes
Enumeration classes derived from built-in types inherit behaviors from these types.

超类
