NEPSetConvergenceTestFunction

Sets a function to compute the error estimate used in the convergence test.

#include "slepcnep.h" 
PetscErrorCode NEPSetConvergenceTestFunction(NEP nep,NEPConvergenceTestFn *conv,void* ctx,PetscErrorCode (*destroy)(void*))

Logically Collective

	nep	- nonlinear eigensolver context obtained from NEPCreate()
	conv	- convergence test function, see NEPConvergenceTestFn for the calling sequence
	ctx	- context for private data for the convergence routine (may be NULL)
	destroy	- a routine for destroying the context (may be NULL)

If the error estimate returned by the convergence test function is less than the tolerance, then the eigenvalue is accepted as converged.
