or
X <> Y
Arguments
X and Y is a scalar/pair/vector/matrix/set. If X or Y is a pair/vector/matrix, the other is a scalar or a pair/vector/matrix of the same size.
Details
If neither X nor Y is a set, conduct the element-by-element comparison of X and Y; return 1 if the elements in X and Y are not the same.
If X and Y are sets, check if X and Y are not identical.
Examples
$ 1 2 3 != 2;
[1,0,1]
