How to Call 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.

The syntax for calling the superclass constructor uses an @ symbol:

Object returned

from superclass

Object being

constructed

obj = objobj = obj@@MySuMySuper Class(SuperClasper Class(SuperClassArgsArguments);uments);

Name of superclass

Superclass constructor

arugment list

In the following class, the MySub object is initialized by the MySuperClass constructor.

The superclass constructor constructs the MySuperClass part of the object using the

specified arguments.

classdef MySub < MySuperClass

methods

function obj = MySub(arg1,arg2,...)

obj = obj@MySuperClass(SuperClassArguments);
