title: Scala vectorization API
body: <p>Is there any Scala API for high performance vectorized computation as in numpy for Python ?</p>
  
  <p>For instance, for summing up two (very large) <code>Array</code>,</p>
  
  <pre><code>vect.sum( Array(1,2,3,...), Array(10,11,12,...) ) == Array(11,13,15,...)
  </code></pre>
