ODE solver using extrapolated IMEX schemes These methods are intended for problems with well-separated time scales, especially when a slow scale is strongly nonlinear such that it is expensive to solve with a fully implicit method. 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>().
<H3><FONT COLOR="#CC3333">Notes</FONT></H3>
The default is a 3-stage scheme, it can be changed with <A HREF="../TS/TSEIMEXSetMaxRows.html#TSEIMEXSetMaxRows">TSEIMEXSetMaxRows</A>() or -ts_eimex_max_rows
<P>
This method currently only works with ODE, for which the stiff part G(t,X,Xdot) has the form Xdot + Ghat(t,X).
