3.
Given the linear system
X, +8x, + 2x, =-3
- 2x, + x2 +5x3 =7
4x, +x, - x3 = 1
Use the Gauss-Seidel iterative method with X")=0.1k to approximate the solution. Compute
3 iterations and calculate ɛa in each iteration using maximum magnitude norm (||x||-).
Hint: First, check whether the method is guaranteed to converge or not. If necessary,
rearrange the order of equations to ensure convergence.
