Let A = 2 1 1 2 1 2 210 (a) Find an LU-decomposition of A. (b) Express A in the form A = L1DU1, where L1 is lower triangular with 1s along the main diagonal, U1 is upper triangular, and D is a diagonal matrix. (c) Express A in the form A = L2U2, where L2 is lower triangular with 1s along the main diagonal and U2 is upper triangular.
