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 Parameter

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().
