in OpenNL
package
Types | |
typedef unspecified_type | NT |
Creation | |
Matrix (int dimension) | |
Create a square matrix initialized with zeros. | |
Matrix (int rows, int columns) | |
Create a rectangular matrix initialized with zeros. | |
Operations | |
int | row_dimension () const |
Return the matrix number of rows. | |
int | column_dimension () const |
Return the matrix number of columns. | |
NT | get_coef (int row, int column) const |
Read access to a matrix coefficient. More... | |
void | add_coef (int row, int column, NT value) |
Write access to a matrix coefficient: a_ij = a_ij + val . More... | |
void | set_coef (int row, int column, NT value, bool new_coef=false) |
Write access to a matrix coefficient: a_ij = val . More... | |
void SparseLinearAlgebraTraits_d::Matrix::add_coef | ( | int | row, |
int | column, | ||
NT | value | ||
) |
Write access to a matrix coefficient: a_ij = a_ij + val
.
0 <= row < row_dimension()
0 <= column < column_dimension()
NT SparseLinearAlgebraTraits_d::Matrix::get_coef | ( | int | row, |
int | column | ||
) | const |
Read access to a matrix coefficient.
0 <= row < row_dimension()
0 <= column < column_dimension()
void SparseLinearAlgebraTraits_d::Matrix::set_coef | ( | int | row, |
int | column, | ||
NT | value, | ||
bool | new_coef = false |
||
) |
Write access to a matrix coefficient: a_ij = val
.
Optimization: Caller can optimize this call by setting new_coef
to true if the coefficient does not already exist in the matrix.
0 <= i < row_dimension()
0 <= j < column_dimension()
