typedef DenseMatrixBase
< Element >::RowIterator | RowIterator |
| The row iterator gives the rows of the matrix in ascending order. Dereferencing the iterator yields a row vector in dense format.
|
typedef DenseMatrixBase
< Element >::ColIterator | ColIterator |
| The columns iterator gives the columns of the matrix in ascending order. Dereferencing the iterator yields a column vector in dense format.

Detailed Description
template<class _Element>
class LinBox::DenseSubmatrix< _Element >
Submatrix of a dense matrix
This matrix type conforms to the same interface as DenseMatrixBase}, except that you cannot resize it. It represents a submatrix of a dense matrix. Upon construction, one can freely manipulate the entries in the DenseSubmatrix, and the corresponding entries in the underlying DenseMatrixBase will be modified.
