Hello, currently in my project I am overloading subsref function and I am little bit confused, because I overload some cases, for other I am still using builtin subsref function.

On example I have created 2 simple classes:

classdef example < handle
  properties
     cellArray 
  end
    methods
        function obj = example()
            obj.cellArray{1} = 'first';
            obj.cellArray{2} = 'second';
        end
        function varargout = subsref(obj, s)
            [varargout{1}] = builtin('subsref', obj, s);
        end
    end
end

and second one:

classdef example2 < handle
    properties
       cellArray 
    end
      methods
          function obj = example2()
              obj.cellArray{1} = 'first';
              obj.cellArray{2} = 'second';
          end
      end
  end

This classes seems similar, but in some cases the results is different, for example:

obj1 = example;
obj2 = example2;

Now, when I want display cellArray as:

>> obj1.cellArray{:}
ans =
first
>> obj2.cellArray{:}
ans =
first
ans =
second
>>

So as can be seen the output of the individual classes is different, and its making me mess in further code development, do you have any tips how to change class example to work exactly like example2 class?
