title: How to get arrows on axes in MATLAB plot?
body: <p>I want to plot something like this:</p>
  
  <pre><code>x = 0:0.01:10;
  f = @(x) 50* 1.6.^(-x-5);
  g = @(x) 50* 1.6.^(+x-10);
  plot(x, f(x));
  hold on
  plot(x, g(x));
  </code></pre>
  
  <p>I can't manage to get axes similar to the ones in this figure:</p>
  
  <p><img src="https://i.stack.imgur.com/U3A4C.png" alt="enter image description here"></p>
  
  <p>I know I can remove the top and right lines like in <a href="https://stackoverflow.com/questions/15553720/matlab-remove-only-top-and-right-ticks-with-leaving-box-on">this question</a>, but I don't know how to get the arrows on the edges.</p>
  
  <p>I don't need the additional annotations, but I would like to remove the ticks on the axes. I know how to do this when the axes are "normal", but I'm not sure if it must be done in another way when the axes are already manipulated.</p>
  
  <p>Does anyone know how to do this?</p>
