The Not Match function » will test whether its arguments are different in any respect - depth, rank, shape or corresponding elements. The result is always a scalar 1 or 0. It is equivalent to ~L ¦ R

The comparisons done by this operation are affected by ŒCT, the comparison tolerance value.
See ¦ Match for more information on how the comparisons are done.
