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.
