Question:

Do 5 steps, starting from x0 = [1    1    1]. Compare with the Gauss–Seidel iteration. Which of the two seems to converge faster? Show the details of your work.

The system in Prob. 9

Data from Prob. 9

Do 5 steps, starting from x0 = [1    1    1]T and using 6S in the computation. Make sure that you solve each equation for the variable that has the largest coefficient (why?). Show the details.

5x1 +   x2  + 2x3 = 19
  x1 + 4x2  - 2x3 =  -2
2x1 + 3x2 + 8x3 = 39
