<h3 class="subsection">D.17.4 Additional <code>umf</code> notes</h3>

<p>The C language API to <code>umf</code> provides very many less frequently
used features that are not part of the virtual code interface, some of
which could be added by minor modifications to the file &lsquo;<tt>umf.c</tt>&rsquo;
in the <code>avram</code> source tree. 
</p>
<p>A set of <code>dl_</code>* and <code>zl_</code>* functions orthogonal to those
presently accessible would enable matrices having billions of rows or
columns by using long integers, but memory requirements on the virtual
code side for problems of that scale are probably prohibitive for the
foreseeable future.
