Thread Subject: problem in calling show function in Object oriented

Hi!
Here is my class below. I am creating points object like pp = point(1,2); and to call show function I do pp.show(); but it give me error "No appropriate method or public field show for class point".

classdef points
    properties
        x
        y
    end
    methods
        function pp= point(x,y)
            this.x=x;
            this.y=y;
        end
        function show()
            disp('hhehe');
        end
    end
end

Kindly help me.

Try something like this:


classdef points
    properties
        x
        y
    end
    methods
        function this = point(x,y)
            this.x = x;
            this.y = y;
        end
        function show(this)
            disp('hhehe');
        end
    end
end


By comparing my code with your code it should be obvious what you did
wrong.

Yes I found the error this = point(x,y) but still same error ??? No appropriate method or public field show for class point. Now I think I am having problem calling class functions on object of the class. Kindly try to run the code and suggest me something to fix this problem.
classdef point
    properties
        x
        y
    end
    methods
        function this= point(x,y)
            this.x=x;
            this.y=y;
        end
        function this.show()
            this.disp('something');
        end
        function this.xchange(var)
            this.x=var;
        end
    end
end

Please don't top post.

You didn't read my code carefully enough. You must pass the object into
show() even though you don't use the object inside this simple example
method.

    function show(this)
        disp('hhehe');
    end

Similarly, xchange should be

    function this = xchange(this,var)
        this.x = var;
    end
