Detailed Description

template<typename T>
class libMesh::LaspackMatrix< T >

The LaspackMatrix class wraps a QMatrix object from the Laspack library.

Currently Laspack only supports real datatypes, so this class is a full specialization of SparseMatrix<T> with T = Real. All overridden virtual functions are documented in sparse_matrix.h.

Constructor & Destructor Documentation

LaspackMatrix() [1/3]

template<typename T >

libMesh::LaspackMatrix< T >::LaspackMatrix

(

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(...).

                                                                  :

Protected implementation of the create_submatrix and reinit_submatrix routines.

Note

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

add() [1/2]

template<typename T >

void libMesh::LaspackMatrix< 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.

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.
