DIM MISMATCH
Your calculator displays the ERR:DIM MISMATCH error
if you are trying to perform an operation that references
one or more lists or matrices whose dimensions do not
match. For example, multiplying L1*L2, where
L1={1,2,3,4,5} and L2={1,2} produces an ERR:DIM
MISMATCH error because the number of elements in
L1 and L2 do not match.
