I had a few minutes to get back to this today.  Looks like I'm helping with the easy parts ;-)

You missed an "end"

classdef ClassA < handle
  properties
    x = 1;
  end
  methods
    function obj = ClassA (x)
      obj.x = x;
    end
  end
end

a(2,2) = ClassA (2)
Error using ClassA (line 7)
Not enough input arguments.

Of course, use this instead:

classdef ClassA < handle
  properties
    x = 1;
  end
  methods
    function obj = ClassA (x)

      if nargin > 0

        obj.x = x;

      end

    end
  end
end
