This option is relevant only for spectrum slicing computations, but it is
ignored if the problem type is <A HREF="../PEP/PEPProblemType.html#PEPProblemType">PEP_HYPERBOLIC</A>.
<P>
This flag is turned on by default, to guarantee that the computed eigenvalues
have the same type (otherwise the computed solution might be wrong). But since
the check is computationally quite expensive, the check may be turned off if
the user knows for sure that all eigenvalues in the requested interval have
the same type.
