NEPGetEigenpair
Gets the i-th solution of the eigenproblem as computed by NEPSolve(). The solution consists in both the eigenvalue and the eigenvector.
Synopsis
#include "slepcnep.h"
PetscErrorCode NEPGetEigenpair(NEP nep,PetscInt i,PetscScalar *eig,Vec V)
Logically Collective on NEP
Input Parameters
| nep | - nonlinear eigensolver context
|
| i | - index of the solution
|
Output Parameters
| eig | - eigenvalue
|
| V | - eigenvector
|
Notes
If PETSc is configured with real scalars, then complex eigenpairs cannot
be obtained. Users should use a complex-scalar configuration. This
behaviour is different to other SLEPc solvers such as EPS.
The index i should be a value between 0 and nconv-1 (see NEPGetConverged()).
Eigenpairs are indexed according to the ordering criterion established
with NEPSetWhichEigenpairs().
