title: Hatching area between two symbolic curves matlab
body: <p>I need to shade the area between symbolic curves and the x axis.</p>
  
  <pre><code>syms x
  
  j(1) = x^2
  j(2) = x^3
  j(3) = x^5
  j(4) = x^6
  
  for i = 1:4
      subplot(2,2,i);
      f(i) = ezplot(j(i),[0,6000]);
      Hatch(f(i))
  end
  </code></pre>
  
  <p>This gives me an error. After looking in the matlab documentation, i end up with codes like</p>
  
  <pre><code>f1 := plot::Function2d(sqrt(x), x = 0..2, Color = RGB::Black):
  </code></pre>
  
  <p>Is this even matlab code? What's with the "::" and ":="? Why does this throw an error?
  Thanks for any help guys!</p>
  
  <p>Thanks!</p>
