missing: TF = lt (A, B)
Less than for missing arrays.
TF = lt (A, B) is the equivalent of the syntax
TF = A < B and returns a logical array of the
same size as the largest input with its elements set to false.
A and B must be size compatible, which translates to they can
be the same size, one can be scalar, or for every dimension, their
dimension sizes must be equal or one of them must be 1.
One of the input arguments may also be any type of array. Any comparison
with missing arrays always returns false.
