PEPStoppingBasic#

Default routine to determine whether the outer eigensolver iteration must be stopped.

Synopsis#

#include "slepcpep.h" 
PetscErrorCode PEPStoppingBasic(PEP pep,PetscInt its,PetscInt max_it,PetscInt nconv,PetscInt nev,PEPConvergedReason *reason,void *ctx)

Collective

Input Parameters#

  • pep - the polynomial eigensolver context

  • its - current number of iterations

  • max_it - maximum number of iterations

  • nconv - number of currently converged eigenpairs

  • nev - number of requested eigenpairs

  • ctx - context (not used here)

Output Parameter#

  • reason - result of the stopping test

Notes#

PEPStoppingBasic() will stop if all requested eigenvalues are converged, or if the maximum number of iterations has been reached.

This is the default stopping test. Use PEPSetStoppingTest() to provide your own test instead of using this one.
