Actually, in numpy, we also have "fancy indexing" similar to Matlab's: In [1]: from numpy import * In [2]: ind = array([3,5,7,2,4,7,8,24]) In [3]: ind[[0, -1]] Out[3]: array([ 3, 24]) -- Robert Kern "I have come to believe that the whole world is an enigma, a harmless enigma that is made terrible by our own mad attempt to interpret it as though it had an underlying truth." -- Umberto Eco -- http://mail.python.org/mailman/listinfo/python-list
