11.15

11.15 of the following three sets of linear equations, identify the
set(s) that you could not solve using an iterative method such as
Gauss-Seidel. Show using any number of iterations that is neces-
sary that your solution does not converge. Clearly state your con-
vergence criteria (how you know it is not converging).
Set One
Set Two
Set Three
8x + 3y + z = 12 x + y + 5z = 7
-óx + 7z = 1
2x + 4y - z = 5
-x + 3y + 5z = 7
x + 4y - z = 4 -2x + 4y - 5z = -3
2y - z = 1
3x + y - z = 4
