For the given matrix/vector pairs, compute the following quantities: a_ii, a_ija_ij, a_ija_jk, a_ijb_j, a_ijb_ib_j, b_ib_j, b_ib_i. For each case, point out whether the result is a scalar, vector or matrix. Note that a_ijb_j is actually the matrix product [a]{b}, while a_ija_jk is the product [a][a].
