title: Solving ODE in two mode with the same result in MATLAB
body: <p>I am using the following commands to solve the ODE function "DynamicFunc":</p>
  
  <pre><code>x0_sim = zeros(12,1);
  time_sim = [0 100];
  options=odeset('AbsTol',1e-9,'RelTol',1e-6);
  [tp,xp]=ode45(@DynamicFunc,time_sim,x0_sim,options);
  </code></pre>
  
  <p>The DynamicFunc can be any function and the code works very well.
  the time of simulation is 0 - 100 seconds. the finals xp will have a size of 3017x12 (i.e. there are 12 states and 3017 trial points). If I want to run this code inside a FOR loop with duration of 1 second, something like this:</p>
  
  <pre><code>x0_sim = zeros(12,1);
  time_sim = [0 1];
  for tt = 1:100
      options=odeset('AbsTol',1e-9,'RelTol',1e-6);
      [tp,xp]=ode45(@DynamicFunc,time_sim,x0_sim,options);
      x0_sim = xp(:,end);
  end
  </code></pre>
  
  <p>The number of final iterations would be so different. How can I make them the same size (for both methods to have the final output with the same vector size)?
  I guess the problem can be related to setting an specific option, but I couldn't find any.</p>
