title: Matlab textscan formatspec delimiter error
body: <p>When reading a large csv file Matlab doesn't recognize ||,|| as a proper delimiter as input argument for textscan. The data is as follows (simplified):</p>
  
  <pre><code>||X||,||Y||,||Z|| (header)
  ||1||,||2||,||4||
  ||4||,||4||,||3||
  </code></pre>
  
  <p>etc.</p>
  
  <p>I use <code>data = textscan(fileID,formatSpec,'Delimiter',',');</code> to read in the data with some format spec <code>'%f %f %f'</code>.</p>
  
  <p>My rubber band solution has been to use 010 editor to replace all '||' with '', making it a proper csv file for matlab, but due to the size of the document (6M lines with approx 35 fields) and the frequency of new documents this is hardly a great solution. </p>
  
  <p>Does anyone know a proper way to import such a file?</p>
