title: Searching a table by a string
body: <p>I am searching a table by a string, but I am not finding the result even though I'm 100% sure it is there. Running <code>genelist</code> prints the table:</p>
  
  <pre><code>&gt;&gt; Untitled
  
  genelist = 
  
      Prot_Family     Gene  
      ___________    _______
  
      'Prx'          'PRDX1'
      'Prx'          'PRDX2'
      'Prx'          'PRDX3'
      'Trx'          'TXN'  
      'Trx'          'TXN2' 
  </code></pre>
  
  <p>But running this command does not find the string: <code>find(strcmp('PRDX2',genelist(:,2)))</code></p>
  
  <p>and <code>strcmp('PRDX2',genelist(:,2))</code> returns 0.</p>
  
  <p>What am I doing wrong?</p>
