Determinants
If matrix A is of order 2 × 3 and B of order 3 × 2, then |
AB, BA both are defined and are equal AB is defined but BA is not defined AB is not defined but BA is defined AB, BA are defined but are not equal |
AB, BA are defined but are not equal |
Matrix Order A 2 × 3 as column (A) = row(B) row(A) = column(B) ⇒ both area defined ⇒ AB, BA both area defined but are not equal |
