Sets a flag to indicate that the matrix has one extra row.
PetscErrorCode DSSetExtraRow(DS ds,PetscBool ext)
Logically Collective on ds
|ds || - the direct solver context
|ext || - a boolean flag
In Krylov methods it is useful that the matrix representing the direct solver
has one extra row, i.e., has dimension (n+1) x n. If this flag is activated, all
transformations applied to the right of the matrix also affect this additional
row. In that case, (n+1) must be less or equal than the leading dimension.
The default is PETSC_FALSE.
