Since vectors in Rn may be regarded as n x 1 matrices, the properties of transposes 1 apply to vectors too. Let A = (27) and x = Compute (Ax), XT AT, xx, and xx. Is ATXT defined? 3 Compute the product AB in two ways: (a) by the definition, where Ab₁ and Ab2 are computed separately, and (b) by the row-column rule for computing AB. 4 -3 1 4 A = - (J), B- (-2) -3 5 = 3 0 1 Since vectors in Rn may be regarded as n x 1 matrices, the properties of transposes 1 apply to vectors too.
