std::ostream & | operator<< (std::ostream &s, const SparseMatrix &m) |
Sparse matrix.
_Scalar | the scalar type, i.e. the type of the coefficients |
See http://www.netlib.org/linalg/html_templates/node91.html for details on the storage scheme.
~SparseMatrix | ( | ) | [inline] |
Destructor
Scalar& fillrand | ( | int | row, | |
int | col | |||
) | [inline] |
Like fill() but with random inner coordinates.
int nonZeros | ( | ) | const [inline] |
void resize | ( | int | rows, | |
int | cols | |||
) | [inline] |
Resizes the matrix to a rows x cols matrix and initializes it to zero
void startFill | ( | int | reserveSize = 1000 |
) | [inline] |
Initializes the filling process of *this
.
reserveSize | approximate number of nonzeros Note that the matrix *this is zero-ed. |
