SparseLinearAlgebraTraits_d::Matrix is a concept of a sparse matrix class.
Assignable DefaultConstructible CGAL::Eigen_sparse_matrix<T> CGAL::Eigen_sparse_symmetric_matrix<T> Types | |
| typedef unspecified_type | Index |
| Index type. | |
| typedef unspecified_type | NT |
Creation | |
| Matrix (Index dimension) | |
| Create a square matrix initialized with zeros. | |
| Matrix (Index rows, Index columns) | |
| Create a rectangular matrix initialized with zeros. | |
Operations | |
| Index | row_dimension () const |
| Return the matrix number of rows. | |
| Index | column_dimension () const |
| Return the matrix number of columns. | |
| NT | get_coef (Index row, Index column) const |
| Read access to a matrix coefficient. | |
| void | add_coef (Index row, Index column, NT value) |
Write access to a matrix coefficient: a_ij = a_ij + val. | |
| void | set_coef (Index row, Index column, NT value, bool new_coef=false) |
Write access to a matrix coefficient: a_ij = val. | |
| void | swap (Matrix &m) |
Swaps the content of *this and m. | |
| Matrix | operator* (const NT &c, const Matrix &M) |
| Multiplication with a scalar. | |
| Matrix | operator+ (const Matrix &M0, const Matrix &M1) |
| Sum of two matrices. | |
Write access to a matrix coefficient: a_ij = a_ij + val.
0 <= row < row_dimension() 0 <= column < column_dimension() Read access to a matrix coefficient.

| ) |
Write access to a matrix coefficient: a_ij = val.
Optimization: Users can indicate that the coefficient does not already exist in the matrix by setting new_coef to true.
