EPSGetErrorEstimate#

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

Synopsis#

#include "slepceps.h" 
PetscErrorCode EPSGetErrorEstimate(EPS eps,PetscInt i,PetscReal *errest)

Not Collective

Input Parameters#

  • eps - the linear 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 EPSComputeError(). See also the users manual for details.
