Hello,

FYI: I've released version 1.0 of ode-initval2 (ODE solver) extension library to GSL. Comments are welcome. It's available at

http://iki.fi/tuomo.keskitalo/gsl/ode-initval2/

Compared to GSL 1.13 ode-initval, ode-initval2 includes new Adams and BDF multistep methods (msadams and msbdf). Implicit steppers rk2imp and rk4imp have been modified to use Newton iteration, and implicit Euler method (rk1imp) has been added. Also, a new driver level has been added to simplify the use of the library.

The main change compared to previous version (ode-initval2-0.9) is in the interfaces. Now the stepper, evolve and control objects include a pointer to the driver object, through which they can communicate.

PS. I took down my ode-initval-additions git repository, since I have not updated it for a while.

Regards,
Tuomo
