EPSSetLeftVectorsWanted
Specifies which eigenvectors are required.
Synopsis
#include "slepceps.h"
PetscErrorCode EPSSetLeftVectorsWanted(EPS eps,PetscBool leftvecs)
Logically 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.
