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
