title: Reshaping cell array in matlab - k*MxN to M x k*N
body: <p>I have a k * MxN cell array that I want to reshape into a M x k * N array. But I want to do this blockwise so that the row structure is preserved.</p>
  
  <pre><code>A B C         --&gt;        A B C G H I M N O
  D E F                    D E F J K L P Q R
  G H I   
  J K L
  M N O
  P Q R
  </code></pre>
  
  <p>Is there a possibility without any loops?</p>
