Last test request. With the following class:

classdef ClassA

  methods
    function obj = ClassA (x)
      if nargin > 0
        obj.x = x;

Execute the following at the prompt:

a(2,2) = ClassA(2)

b = a

c = a(1,1)

c.x = 3

a(1,1).x, b(1,1).x, c.x

a(1,1).x = 4

a(1,1).x, b(1,1).x, c.x

Here it is :

a =

  2x2 ClassA

  Properties:
    x


>> b = a
