MATLAB: Matlab Class property sharing between different classes

Question

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?

Answer 1

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.
