EPSStoppingTestFn#

A prototype of an EPS stopping test function that would be passed to EPSSetStoppingTestFunction()

Synopsis#

PETSC_EXTERN_TYPEDEF typedef PetscErrorCode EPSStoppingTestFn(EPS eps,PetscInt its,PetscInt max_it,PetscInt nconv,PetscInt nev,EPSConvergedReason *reason,void *ctx);

Calling Sequence#

  • eps - the linear eigensolver context

  • its - current number of iterations

  • max_it - maximum number of iterations

  • nconv - number of currently converged eigenpairs

  • nev - number of requested eigenpairs

  • reason - [output] result of the stopping test

  • ctx - [optional] user-defined context for private data for the stopping test routine (may be NULL)
