EPSSetLeftInitialSpace
Specify a basis of vectors that constitute the left initial space, used by twosided 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 twosided
eigensolvers. Users should pass here an approximation of the left eigenspace,
if available.
The same comments in EPSSetInitialSpace() are applicable here.
