In prоblem 1, “NOTA” meаns "Nоne Of The Abоve". 1а (4pt) Which process is the most computаtionally expensive: Forward substitution Back substitution Computing Elimination or reduction Pivoting 1b (4pt) Which of the following statements is TRUE about a matrix norm ||A||? The norm of a nxm matrix with n>m cannot be determined because A is not a square matrix ||A|| measures the magnitude of A in some manner. A negative ||A|| implies that the matrix is well-conditioned The norm of a singular matrix is zero. NOTA 1c (4pt) Given that A is a 4x3 matrix and B is a non-singular 4x4 matrix, which of the following will yield a valid matrix answer? BTATA-1 ABAT B-1BTA A-1BAT NOTA 1d (4pt) Which of the following methods for solving linear systems requires the most work? Cramer’s rule LU Factorization Gaussian elimination Cholesky Factorization NOTA 1e (4pt) For a matrix with condition number cond(A) = 1.4× 107, approximately how many digits of accuracy should be expected when solving the linear system Ax = b using Gaussian elimination with partial pivoting and double precision arithmetic (10-16 machine precision)? 16digit 9 digit 7 digit Cannot be determined NOTA 1f (4pt) Here are 4 matrices A, B, C and D. The row-sum norms of matrix and inverse matrix are given. Which system is well-conditioned according to the condition number? row-sum norm of A = 1011, row-sum norm of A-1 = 1013 row-sum norm of B = 18, row-sum norm of B-1 = 18*1015 row-sum norm of C = 1011, row-sum norm of C-1 = 10-10 row-sum norm of D = 10-10, row-sum norm of D-1 = 1020 NOTA 1g (2pt) True or False: Gauss-Seidel method is not suited for a system of equations whose matrix is dense. 1h (2pt) True or False: Gaussian elimination without pivoting fails only when the matrix is singular. 1i (2pt) True or False: If x is any n-component vector, then the norm 1j (2pt) True or False: If a triangular matrix has a zero entry on its main diagonal, then the matrix is singular. 1k (2pt) True or False: The norm of a singular matrix is zero. (16pt) Given the following three equations 2x1 - x2 - 2x3 = 6 5x1 + 3x2 - 6 x3 = -1 -4x1 + 2x2+ 8 x3 = 8 2a (10pt) Solve by Gauss elimination with partial pivoting. As part of the computation, use the diagonal elements to calculate the determinant. Show all steps of the computation. 2b (6pt) Substitute your results into the original equations to check your answers. (16pt) Consider the Cholesky decomposition for the following positive definite symmetric matrix A:
