EPSSetTolerances

Sets the tolerance and maximum iteration count used by the EPS convergence tests.

Synopsis

#include "slepceps.h" 
PetscErrorCode EPSSetTolerances(EPS eps,PetscReal tol,PetscInt maxits)
Logically Collective

Input Parameters

eps  - the eigensolver context
tol  - the convergence tolerance
maxits  - maximum number of iterations to use

Options Database Keys

-eps_tol <tol>  - Sets the convergence tolerance
-eps_max_it <maxits>  - 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.
