title: Array of doubles in scala
body: <p>I just want a quick way to create an array (or vector) of doubles that doesn't come out as type <code>NumericRange</code>.
  Ive tried </p>
  
  <p><code>val ys = Array(9. to 1. by -1.)</code></p>
  
  <p>But this returns type <code>Array[scala.collection.immutable.NumericRange[Double]]</code></p>
  
  <p>Is there a way to coerce this to regular type <code>Array[Double]</code>?</p>
