<p>
Most of the linear algebra tools deal with dense matrices. However, there is also
a limited amount of support for working with sparse matrices and vectors.
In particular, the dlib tools represent sparse vectors using the container objects
in the C++ STL. For details, see the notes at the top of
<a href="dlib/svm/sparse_vector_abstract.h.html#sparse_vectors">dlib/svm/sparse_vector_abstract.h</a>.
</p>
<p>
Finally, note that all the dense matrix tools can be obtained by #including <tt>&lt;dlib/matrix.h&gt;</tt>
while the sparse vector tools can be obtained by #including <tt>&lt;dlib/sparse_vector.h&gt;</tt>. The
geometry tools can be used by #including <tt>&lt;dlib/geometry.h&gt;</tt>.

In dlib, sparse vectors are represented using the container objects
in the C++ STL. This file defines various useful functions for operating
on these sparse vectors.
