Example 4  Use Gauss-Seidel iteration to attempt solving the linear system  .
Try 10 iterations.  
Observe that something is not working.  In example 5 we will check to see if this matrix is diagonally dominant.   

Solution 4.

Enter the matrix A, vector B and starting vector P.

Use 10 iterations.

Was a solution found ?  Why ?

The matrix A is not diagonally dominant !
