Unformatted text preview: Ux = y , solve Ly = b . Using the solution y , solve Ux = y for x . (Since b is in numerical form, it is not necessary to use L1 or U1 here.) Solved Example S 6.1 . The matrix A can be factored as A = LU , where L = 1 2 1 3 4 113 1 1 and U = 1 1 3115 3 1326 (i) Obtain the matrix A . (ii) Solve Ax = b , where £ 4 13 4 / T , by means of the two triangular systems of equations Ly = b and Ux = y...
