<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&</code> vs. <code>arma::mat const &</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>
