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 - the nonlinear eigensolver context

  • 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.
