title: truncate decimal numbers in matlab?
body: <p>Is there a quick and easy way to truncate a decimal number, say beyond 4 digits, in MATLAB?</p>
  
  <p><code>round()</code> isn't helping, it's still rounding off. I have to use it in for loop, so the quickest way is appreciated. </p>
  
  <p>Thanks for your inputs. </p>
