title: Print elements of ndarray in their storage order
body: <p>To check whether my assumptions on memory layout are correct, I'd sometimes like to print elements of an <code>ndarray</code> exactly in the storage order in memory.</p>
  
  <p>I know <code>flatten</code>, <code>ravel</code>, <code>flat</code>, <code>flatiter</code> but I'm still not sure which function will <strong>truly</strong> reflect the memory order?</p>
