NEPComputeRelativeError

Computes the relative error bound associated with the i-th computed eigenpair.

Synopsis

#include "slepcnep.h" 
PetscErrorCode NEPComputeRelativeError(NEP nep,PetscInt i,PetscReal *error)
Collective on NEP

Input Parameter

nep - the nonlinear eigensolver context
i - the solution index

Output Parameter

error - the relative error bound, computed as ||T(lambda)x||_2/||lambda*x||_2 where lambda is the eigenvalue and x is the eigenvector. If lambda=0 the relative error is computed as ||T(lambda)x||_2/||x||_2.
