<H3><FONT COLOR="#883300">Note</FONT></H3>
The default number of partitions is 1. This means the internal KSP object is shared
among all processes of the <A HREF="../NEP/NEP.html#NEP">NEP</A> communicator. Otherwise, the communicator is split
into npart communicators, so that npart KSP solves proceed simultaneously.
<P>
The realmats flag can be set to true when T(.) is guaranteed to be real
when the argument is a real value, for example, when all matrices in
the split form are real. When set to true, the solver avoids some computations.
