EPSGetLeftVector

Gets the i-th left eigenvector as computed by EPSSolve() (only available in two-sided eigensolvers).

Synopsis

#include "slepceps.h" 
PetscErrorCode EPSGetLeftVector(EPS eps, int i, Vec Wr, Vec Wi)
Not Collective

Input Parameters

eps - eigensolver context
i - index of the solution

Output Parameters

Wr - real part of eigenvector
Wi - imaginary part of eigenvector

Notes

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