NEPComputeError
Computes the error (based on the residual norm) associated with the i-th computed eigenpair.
Synopsis
#include "slepcnep.h"
PetscErrorCode NEPComputeError(NEP nep,PetscInt i,NEPErrorType type,PetscReal *error)
Collective
Input Parameters
| nep | - the nonlinear eigensolver context
|
| i | - the solution index
|
| type | - the type of error to compute
|
Output Parameter
Notes
The error can be computed in various ways, all of them based on the residual
norm computed as ||T(lambda)x||_2 where lambda is the eigenvalue and x is the
eigenvector.
