oski_vecview_t Oski_View() const
Returns the Oski portion of the Multi-Vector.
Epetra_OskiPermutation: A class for storing the permutation performed on a Epetra_OskiMatrix.
Epetra_OskiPermutation()
Default Constructor.
const oski_perm_t * Permutation_
virtual ~Epetra_OskiPermutation()
Destructor.
void ReplacePermutation(const oski_perm_t &InPerm)
Stores a permutation in the data structure.
int PermuteVector(const bool TransA, Epetra_OskiMultiVector &Vector) const
Permutes Vector according to the Permutation. If a transpose is desired it performs that operation.
