VecSetInf#
set infinity into the local part of the vector
Synopsis#
#include "petscvec.h"
PetscErrorCode VecSetInf(Vec xin)
Not Collective
Input Parameters#
xin - the vector
Note#
Deprecated, see VecFlag()
This is used for any subset of MPI processes to indicate an failure in a solver, after the next use of VecNorm() if
KSPCheckNorm() detects an infinity and at least one of the MPI processes has a not converged reason then the KSP
object collectively is labeled as not converged.
This cannot be called if xin has a cached norm available
