+<p>We really heavily on Eigen. Nearly all inputs and outputs are Eigen matrices of
+some kind. However, we currently <em>only</em> support Eigen&#8217;s default column-major
+ordering. That means, we <strong>do not</strong> expect our code to work for matrices using
+the <code>Eigen::RowMajor</code> flag. If you can, change definitions like:
+<code>cpp
+Eigen::Matrix&lt;double, Eigen::Dynamic, 3, Eigen::RowMajor&gt; A;
+</code>
+to
+<code>cpp
+Eigen::Matrix&lt;double, Eigen::Dynamic, 3, Eigen::ColMajor&gt; A;
+// or simply
+Eigen::Matrix&lt;double, Eigen::Dynamic, 3&gt; A;
+</code>
+We hope to fix this, or at least identify which functions are safe (many of
+them probably work just fine). This requires setting up unit testing, which is
+a major <em>todo</em> for our development.</p>
