Main Content

Object array construction and concatenation; heterogeneous arrays

Construct object arrays, reference objects and their properties from arrays, and design class hierarchies that support the formation of heterogeneous (mixed class) arrays.

Topics

Build and Access Object Arrays

• Create and Initialize Object Arrays
  Build object arrays using several different methods.
• Accessing Properties and Methods in Object Arrays
  You can access properties and invoke methods of object arrays as a whole or work with individual elements of the array.
• Determine Array Class
  You can determine the class of an array.

Concatenating Arrays

• Concatenation Methods
  You can concatenate objects into arrays.
• Concatenating Objects of Different Classes
  MATLAB® follows specific rules when you attempt to create an array with objects of different classes.

Class Conversions

• Implicit Class Conversion
  MATLAB can implicitly convert objects to a different class for concatenation, subscripted assignment, property validation, and argument validation.
• Object Converters
  You can convert an object of one class to an object of another class.

Heterogeneous Arrays

• Designing Heterogeneous Class Hierarchies
  Heterogeneous arrays can contain objects of different class, but all objects in the array must derive from a common superclass.
• Heterogeneous Array Constructors
  The class of a heterogeneous object array can change as you add array elements of different classes. You must ensure that constructors return objects that are the same class as the class defining the constructor.
