title: Funny plots in MATLAB: what does lower scale mean?
body: <p>I recently learned the ezplot function in MATLAB. Recently I typed in </p>
  
  <blockquote>
    <p>ezplot('x^y - y^x', [-100 100 -100 100]);</p>
  </blockquote>
  
  <p>and this is what I got;</p>

  <p>Can anyone please tell me whatever is happening ? for lower scaling of x and y ( [ -10 10 -10 10]) there are more patterns in the 2nd 3rd and 4th quadrants. </p>
  
  <p>I was not very sure of the shape of curve, but I did not expect this ! </p>
