How do I know the method working behind ode15i?

Can I get any reference where the method has been explicitly explained?

[Matt J]

Since no refs are given in doc ode15i, it's doubtful that MathWorks wants to disclose it.

Not sure if you have access, but...

Solving 0 = F(t,y(t),y'(t)) in MATLAB by Lawrence F. Shampine, Journal of Numerical Mathematics, Vol.10, No.4, 2002, pp. 291-310.

Thank you Matt. But unfortunately I do not have the access. If don't mind can I get a soft copy of the same. My email id is [e-mail].
