EPSComputeRelativeErrorLeft
Computes the relative error bound associated with the i-th computed eigenvalue and left eigenvector (only available in two-sided eigensolvers).
Synopsis

PetscErrorCode EPSComputeRelativeErrorLeft(EPS eps,PetscInt i,PetscReal *error)
Collective on EPS
Input Parameter
| eps | - the eigensolver context
|
| i | - the solution index
|
Output Parameter
error - the relative error bound, computed as ||y'A-ky'B||_2/||ky||_2 where
k is the eigenvalue and y is the left eigenvector.
If k=0 the relative error is computed as ||y'A||_2/||y||_2.
