Ex 3.1 , 5 Construct a 3 × 4 matrix, whose elements are given by (i) aij = 1/2 |−3i+j| 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&a14@a21&a22&a23&a24@a31&a32&a33&a34)]_(3 × 4) It is given that aij = 1/2 |−3i+j|, Hence, the required matrix is A = [■8(1&1/2&0&1/2@5/2&2&3/2&1@4&7/2&3&5/2)]
