title: KroneckerDelta in matlab
body: <p><a href="http://www.mathworks.com/help/symbolic/mupad_ref/kroneckerdelta.html" rel="nofollow">This link</a> shows that there is a kronecker delta function in matlab.  However:</p>
  
  <pre><code>&gt;&gt; help kroneckerDelta
  
      kroneckerDelta not found
  </code></pre>
  
  <p>I am using R2011b, so maybe this wasn't programmed into the toolkit yet?</p>
  
  <p>EDIT:: It works in MuPad, just not in matlab...</p>
