EPSSetLeftVectorsWanted

Specifies which eigenvectors are required.

Synopsis

#include "slepceps.h" 
PetscErrorCode EPSSetLeftVectorsWanted(EPS eps,PetscTruth leftvecs)
Collective on EPS

Input Parameters

eps - the eigensolver context
leftvecs - whether left eigenvectors are required or not

Options Database Keys

-eps_left_vectors <boolean> - Sets/resets the boolean flag 'leftvecs'

Notes

If the user sets leftvecs=PETSC_TRUE then the solver uses a variant of the algorithm that computes both right and left eigenvectors. This is usually much more costly. This option is not available in all solvers.
