# LMESetTolerances

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

### Synopsis

    #include "slepclme.h"
    PetscErrorCode LMESetTolerances(LME lme,PetscReal tol,PetscInt maxits)

Logically Collective

### Input Parameters

| lme | - the linear matrix equation solver context
| tol | - the convergence tolerance
| maxits | - maximum number of iterations to use

### Options Database Keys

| -lme_tol <tol> | - Sets the convergence tolerance
| -lme_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.
