PEPSetTolerances#
Sets the tolerance and maximum iteration count used by the PEP convergence tests.
Synopsis#
#include "slepcpep.h"
PetscErrorCode PEPSetTolerances(PEP pep,PetscReal tol,PetscInt maxits)
Logically Collective
Input Parameters#
pep - the polynomial eigensolver context
tol - the convergence tolerance
maxits - maximum number of iterations to use
Options Database Keys#
-pep_tol
- Sets the convergence tolerance-pep_max_it
- Sets the maximum number of iterations allowed
Notes#
Use PETSC_CURRENT to retain the current value of any of the parameters. Use PETSC_DETERMINE for either argument to assign a default value computed internally (may be different in each solver). For maxits use PETSC_UMLIMITED to indicate there is no upper bound on this value.
