title: Octave does not plot the function
body: <p>I am preparing a graph of binding protein behavior.</p>
  
  <pre><code>x = linspace(0,1,101)
  y = ( x.*2.2*(10^-4))/(( x.+6.25*(10^-2))*(x.+2.2*(10^-2)))
  plot(x,y)
  </code></pre>
  
  <p>Should result a bell curve(maybe) or a curve but i am getting a linear graph. I had checked with other software and resulting curve that function. Any help please?</p>
