Question

Find Eigenvalues and eigenvectors of the following matrices
1 3
2 -4

3 0 3
0 3 3
3 3 1

For the following equation, use the first three iterations of the Gauss Seidel method to show that some equations do not have a converged answer. Use X=(0,0) as the initial approximation:
x - 5y = -4
7x - y = 6
