Detailed Description
template<class Field_>
class LinBox::SparseMatrix< Field_, SparseMatrixFormat::TPL >
Sparse Matrix in Triples storage.
Sparse matrix representation which stores nonzero entries by i,j,value triples.
Member Function Documentation
◆ write()
| std::ostream & write | ( | std::ostream & | out | ) | const |
- Bug:
- we should not support too many formats
◆ apply()
| OutVector & apply | ( | OutVector & | y, |
| const InVector & | x | ||
| ) | const |
y <- A x.
Performance will generally be best if A is in cacheOpt order, and rowMajor, colMajor orders are generally better than random.
◆ applyTranspose()
| OutVector & applyTranspose | ( | OutVector & | y, |
| const InVector & | x | ||
| ) | const |
y <- A^T x.
Performance will generally be best if A is in cacheOpt order, and rowMajor, colMajor orders are generally better than random.
◆ size()
| size_t size | ( | ) | const |
Returns number of non-zero entries.
- Warning
- (some could be zero, for instance after a rebind...
