I saw a couple different threads hear touching on the issue of different things that look the same.
One issue is data with leading 1 dimensions. These could be eliminated: eliminateLeading1Dimensions=: ,/^:(1=#)^:_ or eL1D=: , $~ $ #~ 1 >./\@:~: $ $ eL1D i. 1 1 2 3 2 3 We could also format the data before testing it: looksSame=: -:&":&eL1D (i. 1 1 2 3) looksSame ": i.2 3 1 For people that have encountered this issue, do any of these variations seem like they could work for you? -- Raul ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
