The linear system 1 X
Chapter 7, Problem 1(choose chapter or problem)
The linear system 1 X| + -X2 1 1 A* + 3 12 has solution (xj, xa)' = (1/6, 1/7)'. a. Solve the linear system using Gaussian elimination with two-digit rounding arithmetic. b. Solve the linear system using the conjugate gradient method (C = C - ' = /) with two-digit rounding arithmetic. c. Which method gives the better answer? d. Choose C -1 = T)_,/2 . Does this choice improve the conjugate gradient method?
