Number of sorted eigenvalues =    2

The selected eigenvalues are:
  1 (   2.0000e+00,   -5.0000e+00)
  2 (   3.0000e+00,   -1.0000e+00)

For the selected eigenvalues,
the reciprocals of projection norms onto the deflating subspaces are
 for left  subspace, rcond =    1.2e-01
 for right subspace, rcond =    1.6e-01

 asymptotic error bound    =    1.9e-13

For the left and right deflating subspaces,
reciprocal condition numbers are:
 for left  subspace, rcond =    4.8e-01
 for right subspace, rcond =    4.7e-01

 approximate error bound   =    4.9e-14
