MATLAB Object-Oriented Programming

For example, the following classdef declares that MyClass is dominant over

ClassName1 and ClassName2.

classdef (InferiorClasses = {?ClassName1,?ClassName2}) MyClass

...

end

The? operator combined with a class name creates a meta.class object. See

metaclass.

The following MATLAB classes are always inferior to classes defined using the classdef

syntax and should not be used in this list.

double, single, int64, uint64, int32, uint32, int16, uint16, int8, uint8, char,

string, logical, cell, struct, and function_handle.

Dominant Class

MATLAB uses class dominance when evaluating expressions involving objects of more

than one class. The dominant class determines:

• Which class method to call when more than one class defines methods with the same
  names.


• The class of arrays that are formed by combining objects of different classes, assuming
  MATLAB can convert the inferior objects to the dominant class.

No Attribute Inheritance

Subclasses do not inherit a superclass InferiorClasses attribute. Only classes

specified in the subclass InferiorClasses attribute are inferior to subclass objects.
