Returns the local and global sizes, and the number of columns.
Synopsis
#include "slepcbv.h"
PetscErrorCode BVGetSizes(BV bv,PetscInt *n,PetscInt *N,PetscInt *m)
Not Collective
Input Parameter
Output Parameters
| n | - the local size

| N | - the global size

| m | - the number of columns

Note
Normal usage requires that bv has already been given its sizes, otherwise
the call fails. However, this function can also be used to determine if
a BV object has been initialized completely (sizes and type). For this,
call with n=NULL and N=NULL, then a return value of m=0 indicates that
the BV object is not ready for use yet.
