title: Filter cell array by some string value
body: <p>I have a cell array, something like this:</p>
  
  <pre><code>A = 
  
      '5523'    '2012-10-26'    '23'    'T'    '17.7'
      '5513'    '2012-10-26'    '23'    'T'    '22.1'
      '5506'    '2012-10-26'    '23'    'C'    '16.2'
  </code></pre>
  
  <p>Now I would like to filter all records that have <code>T</code>. So I would like to get this array:</p>
  
  <pre><code>A = 
  
      '5523'    '2012-10-26'    '23'    'T'    '17.7'
      '5513'    '2012-10-26'    '23'    'T'    '22.1'
  </code></pre>
  
  <p>I could parse all array, but is there any other way?</p>
