Hi,
In MATLAB, assigning an object to a variable or to a cell of a cell array results in the creation of a new copy of that object. This is why when the value property of the object in 'cellArray2' is modified, it does not impact the corresponding object in 'cellArray1'.
To have two variables or cell array cells refer to the same object, handle classes can be utilized. Handle classes in MATLAB exhibit reference behavior, meaning when a handle object is copied, MATLAB creates a new handle to the existing object instead of duplicating the object itself.
Below is an example demonstrating the use of handle classes to attain the desired behavior:
classdef ClassB < handle
properties
value = 0;
end
end
cellArray1{1} = ClassA();
cellArray1{2} = ClassB(); % this is desired object with public variable value = 0
cellArray1{3} = ClassA();
cellArray1{4} = ClassB(); % and this is desired object with public variable value = 0
cellArray1{5} = ClassA();
cellArray2{1} = cellArray1{2}; % adding object on index 2
cellArray2{2} = cellArray1{4}; % adding object on index 4
cellArray2{1}.value = 5;
disp(cellArray1{2}.value); % this displays 5
disp(cellArray2{1}.value); % this displays 5
I hope this helps!
