Compute (e.g., in MATLAB) the inner product matrix V T V , rounding to four significant digits. (ii) (8 pts.) Obtain (by hand) 3 × 3 matrices D (diagonal with positive entries) and U (upper triangular with unit diagonal entries) such that V T V = U T DU (iii) (9 pts.) Determine (by hand) coefficients c ij that yield orthonormal vectors w (1) , w (2) and w (3) , where: w (1) = c 11 v (1) w (2) = c 12 v (1) + c 22 v (2) w (3) = c 13 v (1) + c 23 v (2) + c 33 v (3) Solved Examples S 18.1 ( P 2.39 in textbook).
