title: 'RandStream' is not defined in MATLAB 7.6.0.324?
body: <p>I am trying to use <code>RandStream</code> in MATLAB 7.6.0.324 as below:</p>
  
  <pre><code>randst = RandStream('mrg32k3a', 'Seed', 0);
  </code></pre>
  
  <p>Apparently, <code>RandStream</code> is not defined on MATLAB 7.6.0.324 and I can not find a documentation about it.</p>
  
  <p>How can I set random seed in this version of Matlab then for <code>rand</code> and <code>randperm</code>.</p>
