title: Solving ODE with Simulink in Matlab
body: <p>I need to solve this ODE using Simulink and I don't know how to make it.
  I only know how to do it using ODE solvers.</p>
  
  <pre><code>y'' - y' - 2y = e^(3x)
  
  y(0)=1, y'(0)=2.
  </code></pre>
  
  <p>I rewrote the equation obtaining an ODEs:</p>
  
  <pre><code>y' = f(x,y)
  
  y(x0) = y0
  
  y'1 = y2
  
  y2= e^(3*x) + y' + 2y 
  </code></pre>
  
  <p>Using ODE solver.</p>
  
  <p>If someone can help me to solve this using a Simulink Model I would appreciate it.</p>
  
  <p>I know how to solve it in Matlab using ODE solvers as ode23 and ode23s but I don't know how to do it using a Simulink Model.</p>
  
  <p>Thanks in advance</p>
