Yes, there are many engineering fields where index starts at 0. Partly for the reason you have stated concerning polynomials, especially since this extend to series, which are pervasive in numerical computing. In linear algebra, though, I remember to have always noted matrices indexes in the [1,n] range, not [0,n-1]. In general, I suspect this is much more a tradition than any kind of very reasoned thinking (and conversely, I find most arguments for 0-indexing and against one-indexing rather ... unconvincing. What's awkward is when you have to constantly change from one to the other). cheers, David -- http://mail.python.org/mailman/listinfo/python-list
