#include <MatrixBackend.hpp>

Public Types
using	BaseMatrix = Eigen::SparseMatrix< T, Orientation >
	The matrix type of the underlying base matrix.
using	value_type = typename BaseMatrix::Scalar
	The type of the elements of the DOFMatrix.
using	size_type = typename BaseMatrix::Index
	The index/size - type.

Public Member Functions
	EigenSparseMatrix (DefaultIndexDistribution const &, DefaultIndexDistribution const &)
	Constructor. Constructs new BaseMatrix.
BaseMatrix &	matrix ()
	Return a reference to the data-matrix matrix.
BaseMatrix const &	matrix () const
	Return a reference to the data-matrix matrix.
void	insert (size_type r, size_type c, value_type const &value)
	Returns an update-proxy of the inserter, to insert/update a value at position (r, c) in the matrix. Need an insertionMode inserter, that can be created by init and must be closed by finish after insertion.
template<class Ind , class LocalMat >
void	scatter (Ind const &idx, LocalMat const &mat)
template<class RowInd , class ColInd , class LocalMat >
void	scatter (RowInd const &rows, ColInd const &cols, LocalMat const &mat)
template<class RowInd , class ColInd >
void	zeroRows (RowInd const &rowInd, ColInd const &colInd, bool diag)
	Set all entries of the specified rows to zero and the diagonal element to diag

template<class RowInd , class ColInd >
void	zeroRowsColumnsImpl (RowInd const &rowInd, ColInd const &colInd, bool diag, EigenVector< T > const *x=nullptr, EigenVector< T > *b=nullptr)
	Set all entries of the specified rows and columns to zero and the diagonal element to diag

template<class RowInd , class ColInd >
void	zeroRowsColumns (RowInd const &rowInd, ColInd const &colInd, bool diag, EigenVector< T > const &x, EigenVector< T > &b)
void	init (MatrixSize const &sizes)
	Resize the matrix according to the pattern provided and set all entries to zero.
void	init ()
	Set all matrix entries to zero while keeping the size unchanged.
void	finish ()
	Set the matrix entries from the triplet list and compress the matrix afterwards.
std::size_t	nnz () const
	Return the number of nonzeros in the matrix.
