classdef A < handle
  properties
    b = containers.Map
  end
end

please note that containers.Map is itself a handle class, which is not covered in the copyobj function from Volkmar Glauche. You could recursively call copyobj for handle properties, but then you're facing the next problem of private properties (Maps has private props), which cannot be copied as already mentioned.

In order to copy this class, the "ugly" solution from Barry Ridge is unfortunately the only thing which works in order to deep copy an instance of class A.

any news on this issue from Mathworks?
