Let A be the following invertible matrix with real positive entries:
A=(1289).A = \begin{pmatrix}1 & 2 \\ 8 & 9\end{pmatrix}.A=(1829). Let G be the associated Gauss-Seidel iteration matrix.
What are the two eigen values of G?
0 and 43\frac{4}{3}34
0 and −43\frac{-4}{3}3−4
0 and 169\frac{16}{9}916
43 and −43\frac{4}{3}\ and\ \frac{-4}{3}34 and 3−4
