You can start with ODE45, look through the following page for information on how to set up you system:

Scroll down on the page to see how a non-linear oscillator system was set up for ODE45:

I did it, but still get that error. Can you copy and paste the code and see the error I am getting?

I think I found something online that does what you want: If this doesn't work for you, then please share your code so we can see what is wrong:
