Merge TProfile2D

Real basic problem: I have many root files with the same histograms. I’d like to merge the results in one single file. I know how to do with tree and TH1 but I need to do the same thing with TH2 and TProfile2D. Is there anyone around with some example?
Thanks

Attilio,

TH2 and TProfile2D are also TH1. The Merge operation should also work
with these objects.
