use of ode15i

Dear all, I have to solve an implicit non linear ODE. Does anybody can send me an example on the use of ode15i, as I make mistakes with syntax.

It is much more efficient, if you post your code and we fix the problems.

May I know the exact method that's running behind ode15i? I am curious about the math behind solving the implicit ODEs in general.
