title: Plot smooth cumulative distribution function using MATLAB
body: <p>How is it possible to make the following <a href="http://en.wikipedia.org/wiki/Cumulative_distribution_function" rel="nofollow noreferrer">cumulative distribution function</a> (CDF) curve smoother?</p>
  
  <p>Here's my code, using <a href="http://www.mathworks.se/help/toolbox/stats/cdfplot.html" rel="nofollow noreferrer">cdfplot</a>:</p>
  
  <pre><code>clear all; 
  close all;
  y = [0.75862069 0.666666667 0.882352941 0.875 0.736842105 0.566666667 0.703703704 0.6 0 0.730769231 0.714285714 0.625 0.675 0.693877551 0.731707317 0.558823529 0.679245283 0.740740741 0.785714286 0.789473684 0.615384615 0.6 0.739130435 0.576923077 0 0.75];
  cdfplot(y)
  </code></pre>
  
  <p>The plot looks like:</p>
