Notes
The target is a scalar value used to determine the portion of the spectrum
of interest. It is used in combination with NEPSetWhichEigenpairs().
In the case of complex scalars, a complex value can be provided in the
command line with [+/-][realnumber][+/-]realnumberi with no spaces, e.g.
-nep_target 1.0+2.0i
