title: Transpose a vector into the third dimension
body: <p>Given a vector <code>v = [1 2 3 4 5 6]</code> how do I turn it into: </p>
  
  <pre><code>v = 
      v(:,:,1) =  1
      v(:,:,2) =  2
      v(:,:,3) =  3
      v(:,:,4) =  4
      v(:,:,5) =  5
      v(:,:,6) =  6
  </code></pre>
  
  <p>i.e., transpose between the second (row) and third dimension?</p>
