MATLAB Object-Oriented Programming

calls the DocPolynom plus method (which converts the double, 1, to a DocPolynom

object and then implements the addition of two polynomials). The DocPolynom class has

precedence over the built-in double class.

Defining Precedence

You can specify the relative precedence of classes defined with the classdef syntax by

listing inferior classes in a class attribute. The InferiorClasses property places a class

below other classes in the precedence hierarchy. Define the InferiorClasses property

in the classdef statement:

classdef (InferiorClasses = {?class1,?class2}) myClass

This attribute establishes a relative priority of the class being defined with the order of

the classes listed.

Location in the Hierarchy

If objectA is above objectB in the precedence hierarchy, then the expression

objectA + objectB

calls @classA/plus.m. Conversely, if objectB is above objectA in the precedence

hierarchy, then MATLAB calls @classB/plus.m.
