     Suppose A is an 4 x 4 matrix with the eigenvalues -8, -6, 5, and 1. Suppose you apply the following iterative algorithm:  and choose sigma = 4. Assuming that the algorithm converges on an eigenvector, which eigenvalue of A is associated with that eigenvector? 
  
  Solution
since all eigen values are different , eigen vectors are conveges to corresponding eigen values
