How can I study nonlinear dynamic systems with matlab (and without using Symulink)?

For example, how can I linearize a system around a point or how can I determine the nature of an equilibrium point?

Thanks

For example, how can I solve exercise 1 of this?

  • Are you knowledgeable with the mathematics of liniarization etc, or are you just looking for a ready made tool to do that? – bla Oct 30 '12 at 18:50
  • I would prefer a ready made tool, but it is not so important. I just edited the question with a more specific example... I just want use matlab/octave and not simulink. Thanks @nate – fortea Oct 31 '12 at 14:17

You could try one of the stiff solvers such as ode23s or `ode23tb Here's another link that might be helpful...

  • Ok, thanks. Now I know how to solve nonlinear systems. But how to determine the nature of the zeros of dynamic nonlinear systems? – fortea Oct 31 '12 at 14:16
