STCheckNullSpace
Given a basis vectors object, this function tests each of its constraint vectors to be a nullspace vector of the coefficient matrix of the associated KSP object. All these nullspace vectors are passed to the KSP object.
Synopsis
#include "slepcst.h"
PetscErrorCode STCheckNullSpace(ST st,BV V)

Input Parameters
| st | - the spectral transformation context
|
| V | - basis vectors to be checked

This function allows to handle singular pencils and to solve some problems
in which the nullspace is important (see the users guide for details).
