Question

Consider a system of linear equations, Ax = b given as: x1 + 5x2 + 3x3 = 28 3x1 + 7x2 + 13x3 = 76 12x1 + 3x2 − 5x3 = 1 i. Can you solve the system above using Cholesky decomposition? Explain your answer. ii. Rearrange the rows until A becomes a strictly diagonally dominant matrix. iii. Then, solve the system using the Gauss-Seidel method with x(0) = (1 0 1)T and stop the iteration when max 1≤i≤n |x(k)i − x(k−1)i| < 0.0500
