EPSKrylovSchurGetSubcommInfo
Gets information related to the case of doing spectrum slicing for a computational interval with multiple communicators. 
Synopsis
#include "slepceps.h" 
PetscErrorCode EPSKrylovSchurGetSubcommInfo(EPS eps,PetscInt *k,PetscInt *n,Vec *v)
Collective on the subcommunicator (if v is given)
Input Parameter
|  | eps | - the eigenproblem solver context | 
Output Parameters
|  | k | - index of the subinterval for the calling process | 
|  | n | - number of eigenvalues found in the k-th subinterval | 
|  | v | - a vector owned by processes in the subcommunicator with dimensions
compatible for locally computed eigenvectors (or NULL) | 
Notes
This function is only available for spectrum slicing runs.
The returned Vec should be destroyed by the user.
