I'm getting >> Reference to non-existent field 'speak'. error. Please help.

Hi, I'm a beginner in matlab and using OO programming for first time. Whenever I call function speak from class I get reference to non-existent field 'speak ' error.

classdef dog

    properties 
        name
        breed
        colour   
    end
    
    methods
        function speak(obj)
            disp(obj.name + "says Hi!!!")
        end
    end
end

Your code is fine. Make sure you create an instance of the class, then use that when calling your method. See here.

c=dog;
c.name = "Ruby";

speak(c)

Rubysays Hi!!!

c.speak

Rubysays Hi!!!
