Is there any inbuilt solver in MATLAB that solves a given ODE (order>1) using Crank-Nicolson Method? (Note that I have a system of ODE's, so I might solve each one of them using Crank-Nicolson. I tried ode45, but I am not getting correct results)

  • I think the closest built-in to Crank-Nicolson would be `ode113` which uses an Adams-Bashforth-Moulton method (CN being equivalent to AM-2). However, since `ode45` is an adaptive fourth-order method, I wouldn't expect `ode113` to be a huge improvement (especially since both are designed for non-stiff systems). Could you post an [MCVE](http://stackoverflow.com/help/mcve) along with why you know the solution is wrong? There may be something else amiss aside from the solver. – TroyHaskin Aug 28 '15 at 17:28
  • please post a simple, running version of your code. ODE45 is known to be pretty robust...are you sure you're using ode45 correctly? – anon01 Aug 28 '15 at 17:28

    @anon0909 - It's basic Markdown. The syntax is `[Text here](URL here)`.... so for example [StackOverflow](http://www.stackoverflow.com). Make sure you add the `http://` identifier, or it won't hyperlink properly. – rayryeng Aug 28 '15 at 17:39
