title: Finding but not removing duplicates in Matlab
body: <p>I have a big array in Matlab like this: </p>
  
  <p>A = </p>
  
  <pre><code>{1x5  cell}
  {1x7  cell}
  {1x27 cell}
  {1x11 cell}
    ...
  </code></pre>
  
  <p>where the cells look like this: </p>
  
  <blockquote>
    <blockquote>
      <p>C{1}</p>
    </blockquote>
  </blockquote>
  
  <p>ans = 
  'apple' 'banana' 'kiwi' 'orange' </p>
  
  <p>I want to find where in A find cells containing double information, like:</p>
  
  <blockquote>
    <blockquote>
      <p>C{27}</p>
    </blockquote>
  </blockquote>
  
  <p>ans = 
  'turtle' 'kiwi' 'fox' 'badger' </p>
  
  <p>I.e. here I want to see if C(1) and C(27) has a duplicate word 'kiwi'. 
  So I can manually look at them and decide where I should remove the duplicate where I see fit. </p>
