title: Show Line Number in Error Message
body: <p>On most instances of MATLAB I've used, whenever I had a bug in my code the error message in the command window would show the line number. </p>
  
  <p>However on the computer I am currently using, it shows me only the following:</p>
  
  <p><code>??? Subscripted assignment dimension mismatch.</code></p>
  
  <p>Is there anyway to get the line number to show again instead of <code>????</code>?</p>
