EPSSetLeftInitialSpace
Specify a basis of vectors that constitute the left initial space, used by two-sided solvers to start the left subspace.
Synopsis
#include "slepceps.h"
PetscErrorCode EPSSetLeftInitialSpace(EPS eps,PetscInt n,Vec isl[])
Collective
Input Parameters
| eps | - the eigenproblem solver context
|
| n | - number of vectors
|
| isl | - set of basis vectors of the left initial space
|
Notes
Left initial vectors are used to initiate the left search space in two-sided
eigensolvers. Users should pass here an approximation of the left eigenspace,
if available.
The same comments in EPSSetInitialSpace() are applicable here.
