Object modifications in script

Hello,

I've created a class in MATLAB 2014b. Then I've stored 4 objects of that class in an array. But, if I modify some properties of any of those objects separately, the changes are not updated in the array. I would like to know if there is any kind of structure like GUI handles, where I can store my objects, and where any change in one of those objects is updated on the structure (as when doing guidata(hObject,handles)).

Thanks in advance
