<hr/><a name="details" id="details"></a><h2>Detailed Description</h2>
<div class="textblock"><h3>template<class Matrix, class Trait = typename MatrixTraits<Matrix>::MatrixCategory><br/>
class LinBox::TransposeMatrix< Matrix, Trait ></h3>
<p>Matrix transpose. </p>
<p>This class takes a matrix meeting the <a class="el" href="class_lin_box_1_1_dense_matrix_base.html">DenseMatrixBase</a> archetype and switches the row and column iterators, giving the transpose of the original matrix. It is generic with respect to the matrix given.</p>
<p>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.</p>
<p>This class differs from <a class="el" href="class_lin_box_1_1_transpose.html">Transpose</a> 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 <a class="el" href="class_lin_box_1_1_blackbox_archetype.html">BlackboxArchetype</a> interface. Nor does it make such assumptions about the matrix given.</p>
<p>This class gives a constant matrix as output. It provides no iterators for modification of the data in the matrix.</p>
<p>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 <a class="el" href="class_lin_box_1_1_transpose_matrix.html" title="Matrix transpose.">TransposeMatrix</a> for reading and writing matrices, except for testing purposes. </p>
