> You mean like J's /. adverb? looks interesting... i can kind of see how this could do moving averages but can't see how you could apply it to a table like:
----+----- day | price ----+------ 0 | 1.00 1 | 1.20 2 | 1.15 3 | 1.25 4 | 2.90 5 | 2.70 6 | 2.75 ...but in the following table, the sums and tallies of diagonals contribute to a 3 day moving average: ----+----- day | price ----+------ 0-6 | 1.00 1.20 1.15 1.25 2.90 2.70 2.75 0-6 | 1.00 1.20 1.15 1.25 2.90 2.70 2.75 0-6 | 1.00 1.20 1.15 1.25 2.90 2.70 2.75 am i on the right track? ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
