<h3 class="section">21.2 Linear Algebra with Diagonal and Permutation Matrices</h3>
<p>As has been already said, diagonal and permutation matrices make it
possible to use efficient algorithms while preserving natural linear
algebra syntax. This section describes in detail the operations that
are treated specially when performed on these special matrix objects.
