 maximum volume box
subject to various area and ratio constraints:</p>
<div class="highlight-none"><div class="highlight"><pre>cvx_begin gp
    variables w h d
    maximize( w * h * d )
    subject to
        2*(h*w+h*d) &lt;= Awall;
        w*d &lt;= Afloor;
        alpha &lt;= h/w &gt;= beta;
        gamma &lt;= d/w &lt;= delta;
cvx_end
</pre></div>
</div>
<p>As the example illustrates, CVX supports the construction of
monomials and posynomials using addition, multiplication, division (when
appropriate),
