Detailed Description

template<class Blackbox, class Trait = typename VectorTraits<typename LinBox::Vector<typename Blackbox::Field>::Dense >::VectorCategory>
class LinBox::Submatrix< Blackbox, Trait >

leading principal minor of an existing matrix in a black box fashion.

The matrix itself is not stored in memory. Rather, its apply methods use a vector of field elements, which are used to "multiply" the matrix to a vector.

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 \Ref{LinBox} vector to which to apply the matrix. The third is chosen be default to be the \Ref{LinBox} vector trait of the vector. This class is then specialized for dense and sparse vectors.

Parameters:

Field	\Ref{LinBox} field
Vector	\Ref{LinBox} dense or sparse vector of field elements
Trait	Marker whether to use dense or sparse LinBox vector implementation. This is chosen by a default parameter and partial template specialization.
