title: How to get/see plot of resultant series function/system in matlab?
body: <p>I am using MATLAB for series interconnection of two systems as shown in the code snippet below . How can I see/display the final resultant series transfer function in graph form (<code>sys</code> in my code)?</p>
  
  <pre><code>clc
  clear all
  close all
  num1=[2];
  den1=[3 4];
  num2=[3];
  den2=[4 1];
  sys1=tf(num1,den1);
  sys2=tf(num2,den2);
  sys=series(sys1,sys2);
  </code></pre>
