The Methods Block

Define methods as MATLAB functions within a methods block, inside the classdef

block. The constructor method has the same name as the class and returns an initialized

object of the class. To create an object with property values that are unique to that

instance, assign values to properties in the class constructor. Terminate all method

functions with an end statement.

classdef ClassName

properties

PropertyName

end

methods

function obj = ClassName(arg1,...)

obj.PropertyName = arg1;

...

end

function ordinaryMethod(obj,arg1,...)

...

end

end

methods (Static)

function staticMethod(arg1,...)

...

end

end

end

Method Calling Syntax

MATLAB differs from languages like C++ and Java in that there is no special hidden class

object passed to all methods. You must pass an object of the class explicitly to the method.
