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.
