How to get unique members of an array of handle classes?

I have an array of classdef object derived from handle. It is possible that some of these members could actually point to the same object instance. I would like to get the unique members of this array. I tried the unique function, but it only works for type double.
I realise one solution is to add a method to my class, double(obj), which would allow me to use the unique function. The problem then is getting a value to return from this method. Is there some unique object identifier I can access to do this?
I'm also open to other ways to achieve the same result (a unique array of handle objects).

Since 2013a the unique function supports objects. Before that, you could try a nested loop with calls to isequal, or indeed convert to double (which will only work on pre-2014b).
close all
f=figure;
f2=figure;
h=f;
h2=f;
unique_handle_array=unique([f,f2,h,h2])
%returns handles to figure(1) and figure(2)
