G(t,X,Xdot) = F(t,X) Many br
where G represents the stiff part and F represents the non-stiff part. The user should provide the stiff part Many brof the equation using TSSetIFunction() and the non-stiff part with TSSetRHSFunction(). Many brThis method is designed to be linearly implicit on G and can use an approximate and lagged Jacobian. Many br
Another common form for the system is Many br
y'=f(x)+g(x) Many br
The relationship between F,G and f,g is Many br
G = y'-g(x), F = f(x) Many br
