Consider the linear system Mx = b, where M = ⌈2 -1⌉ ⌊-4 3⌋ and b = ⌈-2⌉ ⌊5⌋. Suppose M = LU, where L and U are lower triangular and upper triangular square matrices, respectively. Consider the following statements: P: If each element of the main diagonal of L is 1, then trace(U) = 3. Q: For any choice of the initial vector x(0), the Jacobi iterates x(k), k = 1, 2, 3, ... converge to the unique solution of the linear system Mx = b. Then, which of the following is true?
