As ux 's shape is (1,lx,ly), ux(:,1,col) is equal to ux(1,1,col) which is a vector with the elements [ux(1,1,2), ... ux(1,1,ly-1)]. Using ":" juste after the reshape seems a lit bit silly... -- Fabrice Silva LMA UPR CNRS 7051 _______________________________________________ NumPy-Discussion mailing list NumPy-Discussion@scipy.org http://mail.scipy.org/mailman/listinfo/numpy-discussion
