title: How to access a list of double values?
body: <p>I have a list of values of the type double[] defined as <code>List &lt;double[]&gt; points</code></p>
  
  <p>The list is given a set of points in the form <code>[[x0, y0], [x1, y1], [x2, y2]...]</code> </p>
  
  <p>How do I access the values x0,y0,x1,y1... using a for loop?</p>
  
  <p>I can access the values in an array using a for loop but can't get my head around how to do so if they are in a List of arrays.</p>
