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,PetscCtxDestroyFn *destroy)
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), see PetscCtxDestroyFn for the calling sequence
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.
