not certain that your problem is convex <em>before</em> you enter it into CVX,
you are using the tool improperly, and your efforts will likely fail.</p>
<p>CVX is <em>not</em> meant for very large problems, so if your problem is very
large (for example, a large image processing or machine learning problem), CVX is unlikely
to work well (or at all). For such problems you will likely need to
directly call a solver, or to develop your own methods, to
