title: Smooth color plots in Matlab
body: <p>How do I create smooth color plots in Matlab?</p>
  
  <p>Here is where I am at now. I use the imagesc function and
  I send you two images. One of them is smoother and better looking
  and that is because I used denser meshgrid to compute the function.
  But still, it is discrete looking. How do I make it smooth?</p>
