The
power method is an iterative technique. The method may not converge very fast.
We can accelerate the convergence as well as get Eigenvalues of magnitude
intermediate between the largest and smallest by shifting. The power method
with its variations is fine for small matrices. However, if a matrix has two
Eigenvalues of equal magnitude, the method fails in the successive
normalization factors alternate between two numbers. The duplicated Eigenvalue
in this case is the square root of the product of the alternating normalisation
factors. If we want all the Eigenvalues for a larger matrix, there is a better way.
