Time stepping with Extrapolated IMEX methods.
<H3><FONT COLOR="#CC3333">Notes</FONT></H3>
The general system is written as
<P>
G(t,X,Xdot) = F(t,X)
<P>
where G represents the stiff part and F represents the non-stiff part. The user should provide the stiff part
of the equation using <A HREF="../TS/TSSetIFunction.html#TSSetIFunction">TSSetIFunction</A>() and the non-stiff part with <A HREF="../TS/TSSetRHSFunction.html#TSSetRHSFunction">TSSetRHSFunction</A>().
This method is designed to be linearly implicit on G and can use an approximate and lagged Jacobian.
<P>
Another common form for the system is
<P>
y'=f(x)+g(x)
<P>
The relationship between F,G and f,g is
<P>
G = y'-g(x), F = f(x)
<P>
