Basic matlab class method [duplicate]

Answer 1

A few problems I noticed:

• you have no constructor
• you do not derive from the handle base class

The constructor is not strictly necessary, but very useful to get to know for when you really want to start developing larger classes. It is used to initialize the obj object, which gets passed around to each and every method. It is quite similar to Python's self, or C++'s this.

So, your corrected class:

classdef Cat < handle

    properties
        meowCount = 0; 
    end

    methods 

        function obj = Cat()
            % all initializations, calls to base class, etc. here,
        end

        function Meow(obj)
            disp('meowww'); 
            obj.meowCount = obj.meowCount + 1;
        end
    end    
end

Demonstration:

>> C = Cat;
>> C.Meow; 
meowww
>> C.meowCount
