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 on NEP
Input Parameter
|  | 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.
