title: Plot a curve rather than a line
body: <p>In matlab, I have a vector, say <code>x</code> and a function of <code>x</code> say <code>y</code>. I want to plot <code>x</code> and <code>y</code> in matlab.</p>
  
  <p>The problem is I want smooth curve (not in a sense of smooth texture but differentiable, and without sharp bends). Matlab, with plot, simply joins the points and the plotted curve has sharp bends.</p>
  
  <p>Is there a way I can resolve this?</p>
