title: Draw lines between matched parts of two sequences
body: <p>I have two different sequences: <code>seq1</code> and <code>seq2</code>.</p>
  
  <pre><code>seq1 = {1,2,3,4}; 
  seq2 = {3,4,6,7,8}; 
  matchedIndexes ={{4,5},{4,4},{4,3},{4,2},{3,1},{2,1},{1,1}}; 
  </code></pre>
  
  <p>I want to draw <code>seq1</code> and <code>seq2</code> along with lines between matched parts using matlab in the same plot.</p>
  
  <p>I have tried the following,</p>
  
  <pre><code>plot(seq1);
  hold on;
  plot(seq2);
  //How to draw lines between matched parts?
  </code></pre>
