EPSSetConvergenceTestFunction

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

#include "slepceps.h" 
PetscErrorCode EPSSetConvergenceTestFunction(EPS eps,EPSConvergenceTestFn *func,void* ctx,PetscCtxDestroyFn *destroy)

Logically Collective

	eps	- eigensolver context obtained from EPSCreate()
	func	- convergence test function, see EPSConvergenceTestFn 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), see PetscCtxDestroyFn for the calling sequence

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