<p>CVX actually converts this internally to this:</p>
<div class="highlight-none"><div class="highlight"><pre>minimize( n*log(det_rootn(X)) )
</pre></div>
</div>
<p>So what you can do instead is simply remove the logarithm, and solve this instead:</p>

<p>The value of <tt class="docutils literal"><span class="pre">log_det(X)</span></tt> can simply be comp
