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.
