NEPSetTolerances#

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

Synopsis#

#include "slepcnep.h" 
PetscErrorCode NEPSetTolerances(NEP nep,PetscReal tol,PetscInt maxits)

Logically Collective

Input Parameters#

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

Options Database Keys#

-nep_tol - Sets the convergence tolerance
-nep_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.
