title: md-virtual-repeat by given number
body: <p>I have some number that coming from database and I want to repeat some list over this number. Lets say <code>366</code> comes from database it has to repeat 366 times.</p>
  
  <p>Below code is working but angular material's <code>md-virtual-repeat</code> does not support <code>track by</code> attribute. Is what I want achiveable?</p>
  
  <pre><code>$scope.number = 5; //Coming from database
  
  $scope.getNumber = function(num) {
  return new Array(num);   
  }
  
  &lt;li ng-repeat="i in getNumber(number) track by $index"&gt;{{$index+1}}&lt;/li&gt;
  </code></pre>
