how can I auto-link two properites in a matlab class

Hi all,

I am relatively new to the object-oriented programming in Matlab (though I have vast experience working with non-object-oriented Matlab).

Here's my question.

I have two parameters in a class that I want to link. For example, y = f(x) and as soon as x changes, 7 should change as well.

As soon as 'x' changes, 'y' should reflect that change as well. The value of 'y' is depended on the opearion of function 'my_func' below. How can I do that?

I am flexibile in the implementation and if it can be done without methods (ie within properties), I am happy with that too.

classdef MyClass    
    properties                
        x
        y
    end
    
    methods          
        function b = my_func(a)            
            if x <10
                y = 1;
            elseif x>=10 && x < 50;
                y=2;
            else 
                y = 3;
            end 
        end
    end
end

Make x and/or y dependent properties, either having the get.y method perform its computations using the value of the x property or having both depend on a third property. For example, if you had area and perimeter properties of an object they could both be Dependent and use the value of a property that stores the coordinates of the vertices of that object.
