Ex 3.1, 5 Construct a 3 × 4 matrix, whose elements are given by (ii) aij = 2i – j, i = 1, 2, 3, and j = 1, 2, 3, 4 Since it is a 3 × 4 matrix it has 3 rows & 4 column Let the required matrix be A , where A = [■8(a11&a12&a13&[email protected]&a22&a23&[email protected]&a32&a33&a34)]_(3 × 4) It is given that aij = 2i – j Hence, the required matrix is A = [■8(1&0&−1&−[email protected]&2&1&[email protected]&4&3&2)]
