Hi everyone, This is slightly related my other thread on how to check if the first and last element were the same.
If I have a=. 2 2 2 2 2 2 2 2 b=. 10 4 $ 2 c=. 2 2 2 2 2 2 4 d=. (10 4 $ 2) , 2 2 2 4 It can be seen that the list 'a' contains all the same number It can be seen that all the rows in matrix 'b' are the same It can be seen that the list 'c' _doesn't_ contain all the same number It can be seen that the last row of the matrix 'd' is different of the result, thus d doesn't contain all the same rows. I am looking for a way to perform a check to see if all the elements are the same or not. I have managed to come up with a solution, but it is very ugly and inefficient Thanks ---------------------------------------------------------------------- For information about J forums see http://www.jsoftware.com/forums.htm
