title: Fill area between 2 curves matlab
body: <p>If i have 3 vectors: mean, mean+standard deviation and mean-standard deviation, how can I fill the space between mean+standard deviation and mean-standard deviation and keep visible the third vetor "mean"?
  I tried like this</p>
  
  <pre><code>h1 = area(x,y_m);
  h2= area(x,y_std1);
  h3= area(x,y_std2);
  </code></pre>
  
  <p>but it fills the entire space under mean+standard deviation.
  In that code, y_m=mean; y_std1=mean+standard deviation; y_std2=mean-standard deviation. These vectors are imported from excel.</p>
