NEPGetErrorEstimate#

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

Synopsis#

#include "slepcnep.h" 
PetscErrorCode NEPGetErrorEstimate(NEP nep,PetscInt i,PetscReal *errest)

Not Collective

Input Parameters#

  • nep - the nonlinear 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 NEPComputeError().
