I am trying to locate specific patterns of a prescribed length within data.
For instance I might want to find occurrences of exactly 2 fives in the following dat=:0 7 8 8 8 9 2 2 5 5 5 3 8 8 8 0 0 5 5 9 6 8 8 8 8 4 0 6 4 2 5 pattern dat 17 the result should ignore the earlier '5 5 5' Now looking for a pattern of exactly 3 eights 3 8 pattern dat 2 12 Again the 4 eights would be ignored I have been trying to use E. but have been confounded by finding a 'universal bounding' of each specific pattern. Ideas and help would be appreciated. David ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
