Matlab Class property sharing between different classes

Hello everyone,

I have two different class implementations:

classdef X                                         classdef Y
    properties                                         properties
        a                                                  a      
        b                                                  c  
    end                                                end                
        ...                                                ...
end                                                end            

I create an object from X and an object from Y. Then, I need the memory to be shared between X.a and Y.a such that if I update X.a, I want Y.a to be updated, not the other properties (b and c) be afffected. I tried different techniques such as creating handle classes for X and Y and made an equality equation such that

X.a = Y.a ;

However, the memory addresses are not shared, only the value is copied from Y class to the X class. If I change X there is no effect on Y class.

What is the method for sharing the memory of properties between different classes?

If you Trying Just copy the Property Value To Share The Value, That Can't Be Done Unless That Value Is A Third Handle Class

classdef ByRefProp < handle
    properties
        value;
    end
end

Now you Can Set

x = X(); y = Y();
y.a = ByRefValue(); 
x.a = y.a;
y.a.value = 'The Quick Brown Fox Jumps Over The Lazy Dog';
disp(x.a.value);

More importantly, You Should Consider The Relationship Between X and Y.

You May Need One To Contain Or Inherit The Other.

Thank you for the quick response, it works!

But i preffered using the matlab.mixin.Copyable class mechanism for the object memory share.

I used the example given in matlab reference in :
