void	UtilitiesAL::create_augmented_block (const MatrixType &A, const MatrixType &Ct, const VectorType &scaling_vector, const double gamma, MatrixType &augmented_matrix)
template<int spacedim, typename VectorType>
void	UtilitiesAL::set_null_space (Teuchos::ParameterList &parameter_list, std::unique_ptr< Epetra_MultiVector > &ptr_distributed_modes, const Epetra_RowMatrix &matrix, const std::vector< VectorType > &modes)
	Set the null space of the matrix using a pre-computed set of vectors. Needed for the AMG preconditioner to work properly with linear elasticity. In particular, parameter_list will be filled by this function.
