EPSKrylovSchurGetSubcommPairs
Gets the i-th eigenpair stored internally in the subcommunicator to which the calling process belongs. 
Synopsis
#include "slepceps.h" 
PetscErrorCode EPSKrylovSchurGetSubcommPairs(EPS eps,PetscInt i,PetscScalar *eig,Vec v)
Collective on the subcommunicator (if v is given)
Input Parameters
|  | eps | - the eigenproblem solver context | 
|  | i | - index of the solution | 
Output Parameters
|  | eig | - the eigenvalue | 
|  | v | - the eigenvector | 
Notes
It is allowed to pass NULL for v if the eigenvector is not required.
Otherwise, the caller must provide a valid Vec objects, i.e.,
it must be created by the calling program with EPSKrylovSchurGetSubcommInfo().
The index i should be a value between 0 and n-1, where n is the number of
vectors in the local subinterval, see EPSKrylovSchurGetSubcommInfo().
