Codes that work include: list1 = {1, 2, 3}; list2 = {4, 5, 6}; Table[list1[[i]] + list2[[i]], {i, Range[Length[list1]]}] {5, 7, 9} Table[list1[[i]] + list2[[i]], {i, Length[list1]}] {5, 7, 9} Table[list1[[i]] + list2[[i]], {i, 3}] {5, 7, 9} OR SIMPLY: list1 + list2 {5, 7, 9} Bobby On Fri, 16 Dec 2011 04:48:57 -0600, Alan Forrester <af17g11 at gmail.com> wrote: > Hello > > I'd like to construct a table by making each element of the table a > function of elements of a couple of lists I have specified, but I'm > getting an error message that seems not to make any sense. > > So I have a couple of lists, like these > list1 = {1,2,3} > list2 = {4,5,6} > > My code for the table I want to construct from those lists is a bit > like this: > Tplus = [list1[i]+list2[i], {i, Range[Length[list1]]}]. > > The error I get claims that i is not an integer or a list of integers, > but Range[Length[list1]] is a list of integers. > > I would appreciate any ideas on what I'm doing wrong. > > Alan Forrester > -- DrMajorBob at yahoo.com
