- :const:`ABS_TOL` may not be appropriate. For example, if we expect
- ``x`` and ``y`` to be within :const:`ABS_TOL` of each other,
- than the inner product of ``L*x`` and ``y`` can be as far apart
- as the spectral norm of ``L`` times the sum of the norms of
- ``x`` and ``y``. Such a comparison is made in :meth:`solution`,
- and in many of our unit tests.
