title: Reshape and rearrange array
body: <p>I have a large array, which looks like this:</p>
  
  <pre><code>1
  4
  5
  3
  6
  2
  7
  4
  3
  </code></pre>
  
  <p>I want to rearrange this array that it looks like this:</p>
  
  <pre><code>7 4 3
  3 6 2
  1 4 5
  </code></pre>
  
  <p>My original array has the size 13700x1, so I cannot do it manually and if I use the reshape function, the array gets shaped in the wrong way:</p>
  
  <pre><code>1 3 7
  4 6 4
  5 2 3
  </code></pre>
  
  <p>I hope my intention is clear. Thanks!</p>
