title: How to create a simple graph Using Matlab
body: <pre><code>sym t;
  a = 10;
  b=10;
  V=6
  v = 2;
  p = 1:.1:20;
  t = ((p./6) + (sqrt(b^2 + (a - p.)^2)/2))
  plot(p,t)
  </code></pre>
  
  <p>I am getting an error whenever I am trying to plot this. 
  The error is, 
  Unbalanced or unexpected parenthesis or bracket. </p>
  
  <p>but I have checked multiple times and I do not have an unbalanced parenthesis. I believe the error has to do with Element-wise matrix multiplication. </p>
