title: Prefix match in MATLAB
body: <p>Hey guys, I have a very simple problem in MATLAB:</p>
  
  <p>I have some strings which are like this:</p>
  
  <pre><code>Pic001
  Pic002
  Pic003
  004
  </code></pre>
  
  <p>Not every string starts with the prefix "Pic". So how can I cut off the part "pic" that only the numbers at the end shall remain to have an equal format for all my strings?</p>
