<div class="textblock"><h3>template<class Blackbox, class Trait = typename VectorTraits<typename LinBox::Vector<typename Blackbox::Field>::Dense >::VectorCategory><br/>
class LinBox::Submatrix< Blackbox, Trait ></h3>
<p>leading principal minor of existing matrix without copying. </p>
<p>leading principal minor of an existing matrix in a black box fashion.</p>
<p>The matrix itself is not stored in memory. Rather, its apply methods use a vector of <a class="el" href="group___fields.html">field</a> elements, which are used to "multiply" the matrix to a vector.</p>
<p>This class has three template parameters. The first is the field in which the arithmetic is to be done. The second is the type of <a class="el" href="namespace_lin_box.html">LinBox</a> vector to which to apply the matrix. The third is chosen be default to be the <a class="el" href="namespace_lin_box.html">LinBox</a> vector trait of the vector. This class is then specialized for dense and sparse vectors.</p>
