title: Scipy solve_ivp vs odeint
body: <p>I have a large system of differential equations I am trying to solve. I get the same results using <code>scipy.odeint</code> and <code>scipy.solve_ivp</code>, however the former is ~17 times faster in my case. I read that <code>solve_ivp</code> is recommended for initial value problems, but can't find more on why I can't use <code>odeint</code> (when it's giving me the same results).</p>
  
  <p>Do I need to use <code>solve_ivp</code> when I am getting the same results as from <code>odeint</code>? When would I use one vs the other?</p>
  
  <p>Thanks.</p>
