EPSComputeRelativeError
Computes the relative error bound associated with the i-th computed eigenpair.
Synopsis
#include "slepceps.h"
PetscErrorCode EPSComputeRelativeError(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 ||Ax-kBx||_2/||kx||_2 where
k is the eigenvalue and x is the eigenvector.
If k=0 the relative error is computed as ||Ax||_2/||x||_2.
