» Not Match

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

             3»3                     (Two scalars are identical)
       0
             3»,3                    (Scalar does not match a vector)
       1
             4 7.1 8 » 4 7.2 8       (Shape is the same but values are not)
       1
             (3 4½¼12)»3 4½¼12       (Two matrices are identical)
       0
             (3 4 ½¼12)»›3 4½¼12     (Simple matrix does not match an enclosed
       1                              version of itself)
             VEC„'ABC' 'DEF'         (Two element vector of 'ABC' 'DEF)
             VEC
       ABC DEF
             ½VEC                    (Length 2)
       2
             VEC»'ABCDEF'            (Does not match the 6 element vector
       1                              'ABCDEF')

The comparisons done by this operation are affected by ŒCT, the comparison tolerance value.
