A positive value of reason indicates that the iteration has finished successfully
(converged), and a negative value indicates an error condition (diverged). If
the iteration needs to be continued, reason must be set to PEP_CONVERGED_ITERATING
(zero).
<P>
<A HREF="../PEP/PEPStoppingBasic.html#PEPStoppingBasic">PEPStoppingBasic</A>() will stop if all requested eigenvalues are converged, or if
the maximum number of iterations has been reached.
<P>
Use <A HREF="../PEP/PEPSetStoppingTest.html#PEPSetStoppingTest">PEPSetStoppingTest</A>() to provide your own test instead of using this one.
