EPSGetValue

Gets the i-th eigenvalue as computed by EPSSolve().

Synopsis

#include "slepceps.h" 
PetscErrorCode EPSGetValue(EPS eps, int i, PetscScalar *eigr, PetscScalar *eigi)
Not Collective

Input Parameters

eps - eigensolver context
i - index of the solution

Output Parameters

eigr - real part of eigenvalue
eigi - imaginary part of eigenvalue

Notes

If the eigenvalue is real, then eigi is set to zero. In the complex case (e.g. with BOPT=O_complex) the eigenvalue is stored directly in eigr (eigi is set to zero).

The index i should be a value between 0 and nconv (see EPSGetConverged()). Eigenpairs are indexed according to the ordering criterion established with EPSSetWhichEigenpairs().
