Raw iterator
The raw iterator is a method for accessing all entries in the matrix in some unspecified order. This can be used, e.g. to reduce all matrix entries modulo a prime before passing the matrix into an algorithm.
Iterator	Begin ()

Iterator	End ()

ConstIterator	Begin () const

ConstIterator	End () const

Raw Indexed iterator.
Like the raw iterator, the indexed iterator is a method for accessing all entries in the matrix in some unspecified order. At each position of the the indexed iterator, it also provides the row and column indices of the currently referenced entry. This is provided through it's rowIndex() and colIndex() functions.
Matrix &	_Mat

IndexedIterator	IndexedBegin ()

IndexedIterator	IndexedEnd ()

ConstIndexedIterator	IndexedBegin () const

Detailed Description

template<class Matrix, class Trait = typename MatrixTraits<Matrix>::MatrixCategory>
class LinBox::TransposeMatrix< Matrix, Trait >

Matrix transpose.

This class takes a matrix meeting the BlasMatrix archetype and switches the row and column iterators, giving the transpose of the original matrix. It is generic with respect to the matrix given.

If the matrix given has limited iterators, then its transpose will have limited iterators as well. In particular, if the matrix given has only row iterators, then the transpose object will have only column iterators, and vice versa.

This class differs from Transpose in that it constructs a full matrix representation, with row and/or column iterators. It does not include any logic for matrix-vector products, and does not meet the BlackboxArchetype interface. Nor does it make such assumptions about the matrix given.

This class gives a constant matrix as output. It provides no iterators for modification of the data in the matrix.

The input/output functionality of this class passes requests directly through to the underlying matrix. In particular, the output will be the transpose of the matrix expected and the input will expect the transpose of the matrix given. Thus, it is not recommended to use TransposeMatrix for reading and writing matrices, except for testing purposes.
