PEPGetErrorEstimate#

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

Synopsis#

#include "slepcpep.h" 
PetscErrorCode PEPGetErrorEstimate(PEP pep,PetscInt i,PetscReal *errest)

Not Collective

Input Parameters#

  • pep - the polynomial eigensolver context

  • i - index of eigenpair

Output Parameter#

  • errest - the error estimate

Note#

This is the error estimate used internally by the eigensolver. The actual error bound can be computed with PEPComputeError().
