What's the forward difference of one element? --Mwn3d 07:17, 11 January 2008 (MST)
- With regard to pure mathematics I suppose it is undefined. It is natural, however, to extend it by definition so that the forward difference of a list of one element is the empty list. That's how the J code resolves it, too. --TBH 07:31, 11 January 2008 (MST)
- I guess the FD of an empty list should just be another empty list then? These corner cases always get you. --Mwn3d 07:39, 11 January 2008 (MST)
