NEPSetTolerances

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

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

Logically Collective

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

	-nep_tol <tol>	- Sets the convergence tolerance
	-nep_max_it <maxits>	- Sets the maximum number of iterations allowed

Use PETSC_DEFAULT for either argument to assign a reasonably good value.
