Specify a basis of vectors that constitute the left initial space, used by two-sided solvers to start the left subspace.


#include "slepceps.h" 
PetscErrorCode EPSSetLeftInitialSpace(EPS eps,PetscInt n,Vec isl[])
Collective on eps

Input Parameters

eps  - the eigenproblem solver context
n  - number of vectors
isl  - set of basis vectors of the left initial space


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.
