SVDStoppingTestFn#

A prototype of an SVD stopping test function that would be passed to SVDSetStoppingTestFunction()

Synopsis#

PETSC_EXTERN_TYPEDEF typedef PetscErrorCode SVDStoppingTestFn(SVD svd,PetscInt its,PetscInt max_it,PetscInt nconv,PetscInt nsv,SVDConvergedReason *reason,void *ctx);

Calling Sequence#

  • svd - the singular value solver context

  • its - current number of iterations

  • max_it - maximum number of iterations

  • nconv - number of currently converged singular triplets

  • nsv - number of requested singular triplets

  • reason - [output] result of the stopping test

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