It always returns 0 or 1, and never causes an error. If both arguments are atoms then it is identical to `=`, and if one is an atom and the other an array then it returns 0. If both arguments are arrays then it returns 1 only if they have the same shape and all pairs of corresponding elements match. Fill elements aren't taken into account, so that arrays that match might still differ in behavior. **Not Match** simply returns the complement of Match, `Β¬β‘`. -Monadic search functions compare the major cells of `π©` to each other. `π©` must have rank at least 1.
