The target is a scalar value used to determine the portion of the spectrum
of interest. It is used in combination with <A HREF="../PEP/PEPSetWhichEigenpairs.html#PEPSetWhichEigenpairs">PEPSetWhichEigenpairs</A>().
<P>
In the case of complex scalars, a complex value can be provided in the
command line with [+/-][realnumber][+/-]realnumberi with no spaces, e.g.
-pep_target 1.0+2.0i
