Detailed Description
template<class _Field, class _Row = typename LinBox::Vector<_Field>::Sparse>
class LinBox::SparseMatrix< _Field, _Row >
vector of sparse rows.
This is a generic black box for a sparse matrix. It inherits LinBox::SparseMatrixBase, which implements all of the underlying accessors and iterators.
Constructor & Destructor Documentation
| SparseMatrix | ( | const Field & | F, |
| size_t | m = 0, |
||
| size_t | n = 0 |
||
| ) | [inline] |
Constructor. Builds a zero m x n matrix Note: the copy constructor and operator= will work as intended because of STL's container design
- Parameters:
-
F Field over which entries exist m Row dimension n Column dimension
| SparseMatrix | ( | const Field & | F, |
| VectStream & | stream | ||
| ) | [inline] |
Constructor from a vector stream
- Parameters:
-
F Field over which entries exist stream Stream with which to generate row vectors
| SparseMatrix | ( | MatrixStream< Field > & | ms | ) | [inline] |
Constructor from a MatrixStream
- Parameters:
-
ms A matrix stream properly initialized
| SparseMatrix | ( | const SparseMatrix< Field, Row > & | B | ) | [inline] |
Copy constructor
| SparseMatrix | ( | const SparseMatrix< Field, VectorType > & | B | ) | [inline] |
Row type Converter constructor
| ~SparseMatrix | ( | ) | [inline] |
Destructor.
