Constructor & Destructor Documentation

EpetraMatrix() [1/4]

template<typename T >

libMesh::EpetraMatrix< T >::EpetraMatrix

(

const Parallel::Communicator &

comm

)

Constructor; initializes the matrix to be empty, without any structure, i.e.

the matrix is not usable at all. This constructor is therefore only useful for matrices which are members of a class. All other matrices should be created at a point in the data flow where all necessary information is available.

You have to initialize the matrix before usage with init(...).

Definition at line 298 of file trilinos_epetra_matrix.C.

                                                               :
  SparseMatrix<T>(comm),
  _destroy_mat_on_exit(true),
  _use_transpose(false)
{}

EpetraMatrix() [2/4]

template<typename T >

libMesh::EpetraMatrix< T >::EpetraMatrix	(	Epetra_FECrsMatrix *	m,
		const Parallel::Communicator &	comm
	)

Constructor.

Creates a EpetraMatrix assuming you already have a valid Epetra_FECrsMatrix object. In this case, m is NOT destroyed by the EpetraMatrix destructor when this object goes out of scope. This allows ownership of m to remain with the original creator, and to simply provide additional functionality with the EpetraMatrix.

                                                                 :
  SparseMatrix<T>(comm),
  _destroy_mat_on_exit(false),
  _use_transpose(false) // dumb guess is the best we can do...
{
  this->_mat = m;
  this->_is_initialized = true;

This class manages the lifetime of an Epetra_FECrsMatrix manually, so we don't want to allow any automatic copy/move functions to be generated, and we can't default the destructor.

_get_submatrix()

inlineprotectedvirtualinherited

Protected implementation of the create_submatrix and reinit_submatrix routines.

Note

This function must be overridden in derived classes for it to work properly!

Reimplemented in libMesh::PetscMatrix< T >.

add() [1/2]

template<typename T >

void libMesh::EpetraMatrix< T >::add ( const numeric_index_type  i, const numeric_index_type  j, const T  value  )

overridevirtual

Add value to the element (i,j).

Throws an error if the entry does not exist. Zero values can be "added" to non-existent entries.

Implements libMesh::SparseMatrix< T >.

add() [2/2]

template<typename T >

void libMesh::EpetraMatrix< T >::add ( const T  a, const SparseMatrix< T > &  X  )

overridevirtual

Compute A += a*X for scalar a, matrix X.

Note

It is advisable to not only allocate appropriate memory with init(), but also explicitly zero the terms of this whenever you add a non-zero value to X.

X will be closed, if not already done, before performing any work.

Add the full matrix dm to the SparseMatrix.

This function is similar to the one above, but it allows you to reuse the existing sparsity pattern of "submatrix" instead of reallocating it again.

This should hopefully be more efficient if you are frequently extracting submatrices of the same size.
