title: MatLab ode45 minimal time step
body: <p>I'm trying to solve differential equations with MatLab and ode45 function.
  The question is how can I change minimal step size? I want to make it bigger to avoid too small steps.
  I'm tryin to do it like this:</p>
  
  <pre><code>tspan = [3, 4]; (boundaries of time line)
  [t, q] = ode45('dqdt2', tspan, q0);
  </code></pre>
  
  <ul>
  <li>t - time</li>
  <li>q - solution to find</li>
  <li>dqdt2 - my file with function</li>
  <li>q0 - initial conditions</li>
  </ul>
