<p>After I merge this, do you mind if I change the ordering of the <code>const</code> to be the way the rest of the code is?  i.e. <code>const arma::mat&amp;</code> vs. <code>arma::mat const &amp;</code>.  They both do exactly the same thing.  If you have a specific reason for ordering it the way you have, that's fine too; I just try to make things look the same. :)</p>
