<p>A few days ago, <a target="_blank" rel="nofollow" href="http://conradsanderson.id.au/">Conrad</a> released <a target="_blank" rel="nofollow" href="http://arma.sourceforge.net/">Armadillo</a> 7.500.0. The corresponding <a target="_blank" rel="nofollow" href="http://dirk.eddelbuettel.com/code/rcpp.armadillo.html">RcppArmadillo</a> release 0.7.500.0.0 is now on <a target="_blank" rel="nofollow" href="https://cran.r-project.org/">CRAN</a> (and will get into <a target="_blank" rel="nofollow" href="http://www.debian.org/">Debian</a> shortly).</p>
<p><a target="_blank" rel="nofollow" href="http://arma.sourceforge.net/">Armadillo</a> is a powerful and expressive C++ template library for linear algebra aiming towards a good balance between speed and ease of use with a syntax deliberately close to a Matlab. <a target="_blank" rel="nofollow" href="http://dirk.eddelbuettel.com/code/rcpp.armadillo.html">RcppArmadillo</a> integrates this library with the <a target="_blank" rel="nofollow" href="https://www.r-project.org/">R</a> environment and language–and is widely used by (currently) 274 other packages on <a target="_blank" rel="nofollow" href="https://cran.r-project.org/">CRAN</a>.</p>
<p>Changes in this release relative to the previous <a target="_blank" rel="nofollow" href="http://cran.r-project.org/">CRAN</a> release are as follows:</p>
<blockquote>
<h4>Changes in RcppArmadillo version 0.7.500.0.0 (2016-10-20)</h4>
<ul>
<li>
<p>Upgraded to Armadillo release 7.500.0 (Coup d’Etat)</p>

</li>
<li>
<p>Expanded <code>each_slice()</code> to support matrix multiplication</p>
</li>
</ul>
</li>
</ul>
