How can I create variables / properties for an object of same type, as of the object's class in MATLAB?

I am trying to build a recursive function which will help in creating a object of a custom Class, and have children of the type same as of the custom Class.

Also, I would like to create grand child of the same object and so on.

For Example, I have an object of type "ClassA" declared as "ABC" with a name "abc". I want to have to create an object of "classA" named "xyz", which will be child of "abc".

Later I want to create an object of "classA" named "child_of_xyz" which will be child of "xyz" object, and a grand child of "abc".

You can define a custom Class as mentioned below:

classdef classA < handle

   properties

      child classA

      Name

   end

   methods

       function obj = classA(name)

          obj.Name =  name;

       end

       function obj = populateChildForThis(obj,value)

            obj.child = classA(value);             

       end

   end

end

Details of class "classA"

- Note: "classA" is derived from the handle class. Please refer to the documentation link <https://www.mathworks.com/help/matlab/matlab_oop/comparing-handle-and-value-classes.html#bu6t672 here > for more details.

- In this class there are 2 properties.

1. Name - We can store the name of the object which we can use as a reference.

2. child - This property is of the same type as of the object itself (i.e. classA). We can store the reference of the child in here.

- In this class there is one constructor we are using to assign the name to the object we are creating.

- The method "populateChildForThis" is used to create the child of the object "obj" with the name "value".

- If you want to test this class, please run the below code scripts sequentially.

>> ABC = classA("abc")

ABC = populateChildForThis(ABC,"xyz")

XYZ = ABC.child

XYZ= populateChildForThis(XYZ,"child_of_xyz")

ABC.child.child
