//==============================================================================
int Ifpack_ReorderFilter::
Multiply(bool TransA, const Epetra_MultiVector& X, 
         Epetra_MultiVector& Y) const

  // need two additional vectors

  Epetra_MultiVector Ytilde(Y.Map(),Y.NumVectors());
  // bring X back to original ordering
  Reordering_->Pinv(X,Xtilde);
  // apply original matrix
  IFPACK_CHK_ERR(Matrix()->Multiply(TransA,Xtilde,Ytilde));
  // now reorder result
  Reordering_->P(Ytilde,Y);
