title: Creating .txt output with string and numbers in matlab
body: <p>I'm new to matlab.
  I have multiple <code>.txt</code> files with up to 1000 each with a content as the following:</p>
  
  <blockquote>
    <p>09.10.2015,08:17:02,51683,8,3286,78,6,7,0,13</p>
  </blockquote>
  
  <p>I'm trying to merge all <code>.txt</code> files together to create one big <code>.txt</code> file that I can use for further analysis.
  The <code>.txt</code> files have the same number of columns but different number of lines.
  I don't have difficulties merging the files if there are the numbers only but the date and time causes difficulties. 
  Really would appreciate any help you could give.</p>
