#include "petscmat.h" PetscErrorCode MatFactorGetErrorZeroPivot(Mat mat,PetscReal *pivot,PetscInt *row)Logically Collective on Mat
| pivot | - the pivot value computed | |
| row | - the row that the zero pivot occurred. Note that this row must be interpreted carefully due to row reorderings and which processes the share the matrix |
Notes: This routine does not work for factorizations done with external packages. This routine should only be called if MatGetFactorError() returns a value of MAT_FACTOR_NUMERIC_ZEROPIVOT
This can be called on non-factored matrices that come from, for example, matrices used in SOR.
