Dear J enthusiasts, I am wondering what is the preferable way to determine the rank of a matrix in J. I would expect here below
]m=: 3 3 $ 1 2 3 5 4 6 9 7 8 1 2 3 5 4 6 9 7 8 rank m 3 ]m=: 3 3 $ 1 2 3 2 4 6 9 7 8 1 2 3 2 4 6 9 7 8 rank m 2 Thanks and cheers Pawel Jakubas ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
