Playing with J for C and got to "Apply On Specified Partitions: Dyad u;.1 and u;.2". Replaced the < with +/ and it didn't sum the rows. After looking at the result a little more closely I discovered that each cell contained a table instead of a row. (0 1 1;1 0 0 1) <;.1 i. 3 4 +------+--+ |4 5 6 |7 | +------+--+ |8 9 10|11| +------+--+ (0 1 1;1 0 0 1) (<@$);.1 i. 3 4 +---+---+ |1 3|1 1| +---+---+ |1 3|1 1| +---+---+
I can't figure out why. Also, in the Dictionary for Cut it describes the rank as "_ 1/2 _". What does the "1/2" mean? Needless to say, I still have a long way go to fully understand Cut. ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
