Returns the error estimate associated to the i-th computed eigenpair.

Synopsis

#include "slepcpep.h" 
#include "slepcbv.h" 
PetscErrorCode PEPGetErrorEstimate(PEP pep,PetscInt i,PetscReal *errest)
Not Collective

Input Parameters

pep  - polynomial eigensolver context
i  - index of eigenpair

Output Parameter

errest  - the error estimate

Notes

This is the error estimate used internally by the eigensolver. The actual error bound can be computed with PEPComputeError(). See also the users manual for details.
