+
+<h2 id="DESCRIPTION">DESCRIPTION</h2>
+
+<p><code>pm</code> computes the leading eigenvalue and the corresponding eigenvector
+of the matrix given as input, using the Power Method. In particular,
+this implementation uses the Rayleigh iteration, which allows faster
+convergence on undirected graphs.</p>
+
+<h2 id="PARAMETERS">PARAMETERS</h2>
+
+<dl>
+<dt><var>graph_in</var></dt><dd><p> input graph (edge list) if equal to <code>-</code> (dash), read the edge list
+ from STDIN (standard input).</p></dd>
+<dt class="flush"><var>is_dir</var></dt><dd><p> set either to <code>0</code> (zero) for undirected graphs, or to <code>1</code> (one)
+ for directed graphs.</p></dd>
+<dt class="flush"><var>eps</var></dt><dd><p> Required relative error on the approximation of the leading
+ eigenvalue. The program terminates when the relative change in the
+ approximation of the eigenvalue is smaller than <code>eps</code></p></dd>
+</dl>
+
+
+<h2 id="EXAMPLES">EXAMPLES</h2>
+
+<p>The following command:</p>
+
+<pre><code> $ pm er_1000_5000.net 0 0.0000001
+</code></pre>
+
+<p>computes the leading eigenvalue and the corresponding eigenvector of
+the undirected graph stored in the file <code>er_1000_5000.txt</code>. We can
+store the leading eigenvector in a file, e.g. by using the command:</p>
+
+<pre><code> $ pm er_1000_5000.net 0 0.0000001 &gt; er_1000_5000.net_eig
+ 11.0335794552533
+ $
+</code></pre>
+
+<p>which will save the leading eigenvector in the file
+<code>er_1000_5000.net_eig</code>, one component for each row, and shown on
+output the leading eigenvalue of the graph.</p>
