SNESSetConvergenceTest

Sets the function that is to be used to test for convergence of the nonlinear iterative solution.

#include "petscsnes.h"  
int SNESSetConvergenceTest(SNES snes,int (*func)(SNES,PetscReal,PetscReal,PetscReal,SNESConvergedReason*,void*),void *cctx)

Collective on SNES

	snes	- the SNES context
	func	- routine to test for convergence
	cctx	- [optional] context for private data for the convergence routine (may be PETSC_NULL)

    int func (SNES snes,PetscReal xnorm,PetscReal gnorm,PetscReal f,SNESConvergedReason *reason,void *cctx)

	snes	- the SNES context
	cctx	- [optional] convergence context
	reason	- reason for convergence/divergence
	xnorm	- 2-norm of current iterate
	gnorm	- 2-norm of current step
	f	- 2-norm of function
