See numpy.bincount (for integers >= 0) if you mean 'without writing looping code in Python' or please specify your question. > Question 2: is it possible to compute a "moving maximum" without python > looping > > ia=array([4,2,1,5,3,2,2,0,1,1]) > -> mvmax(ia,3) -> > [4,4,4,5,5,5,3,2,2,1]) I haven't seen a ready solution but this can be easily converted into Pyrex/C looping. cheers, fw -- http://mail.python.org/mailman/listinfo/python-list
