NEPSetStoppingTestFunction

Sets a function to decide when to stop the outer iteration of the eigensolver.

Synopsis

#include "slepcnep.h" 
PetscErrorCode NEPSetStoppingTestFunction(NEP nep,NEPStoppingTestFn *stop,void* ctx,PetscErrorCode (*destroy)(void*))

Logically Collective

Input Parameters

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

Note

Normal usage is to first call the default routine NEPStoppingBasic() and then set reason to NEP_CONVERGED_USER if some user-defined conditions have been met. To let the eigensolver continue iterating, the result must be left as NEP_CONVERGED_ITERATING.
