MatMissingDiagonal#

Determine if sparse matrix is missing a diagonal entry (or block entry for MATBAIJ and MATSBAIJ matrices) in the nonzero structure

Synopsis#

#include "petscmat.h" 
PetscErrorCode MatMissingDiagonal(Mat mat, PetscBool *missing, PetscInt *dd)

Not Collective

Input Parameter#

  • mat - the matrix

Output Parameters#

  • missing - is any diagonal entry missing

  • dd - first diagonal entry that is missing (optional) on this process

Note#

This does not return diagonal entries that are in the nonzero structure but happen to have a zero numerical value
