EPSSetStoppingTestFunction

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

Synopsis

#include "slepceps.h" 
PetscErrorCode EPSSetStoppingTestFunction(EPS eps,EPSStoppingTestFn *func,void* ctx,PetscErrorCode (*destroy)(void*))

Logically Collective

Input Parameters

	eps	- eigensolver context obtained from EPSCreate()
	func	- stopping test function, see EPSStoppingTestFn 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 EPSStoppingBasic() and then set reason to EPS_CONVERGED_USER if some user-defined conditions have been met. To let the eigensolver continue iterating, the result must be left as EPS_CONVERGED_ITERATING.
