 F02EKF Example Program Results

  Arnoldi basis vectors used:  20
  The following Ritz values (mu) are related to the
  true eigenvalues (lambda) by lambda = sigma + 1/mu

  Iteration number    1
  Ritz values converged so far (   2) and their Ritz estimates:
     1 (  0.56992E+00,  0.88081E+00)   0.13008E-19
     2 (  0.56992E+00, -0.88081E+00)   0.13008E-19
  Next (unconverged) Ritz value:
     3 (  0.60777E+00,  0.00000E+00)

 The    5 Ritz values of closest to   0.55000E+01 are:

        1     (   0.60178E+01 ,  -0.80028E+00 )
        2     (   0.60178E+01 ,   0.80028E+00 )
        3     (   0.43431E+01 ,  -0.19456E+01 )
        4     (   0.43431E+01 ,   0.19456E+01 )
        5     (   0.71453E+01 ,   0.00000E+00 )
