I came up with a bit of a hack for doing this. It uses file-handling, and therefore is not so elegant, but it seems to work. Just add this method to whatever class you want to copy:

function new = copy(this)
save('temp.mat', 'this');
Foo = load('temp.mat');
new = Foo.this;
delete('temp.mat');
end

Example usage (assumes copy() is a method in class MyClass):
A = MyClass();
B = A.copy();

If modifying the class is an option, then have your clone method in your
class instantiate a new empty handle object and set the appropriate
properties. Remember, inside a class method, you have access to all the
properties of the object. If you don't want to hard-code the list of
properties, you could always make use of the meta.class object for your
object along with dynamic "field" names (or your class's GET and SET
methods, or whatever other property access system you've devised.)
