I am no expert on licenses, can somebody please tell briefly what their license allows us to do with the source code? > I would enjoy hearing what anybody has to say about CVODE/Sundials. Well, Alan Hindmarsh is a definitive author on multistep methods and the package looks quite promising. I will definitely look up those numerical methods. > I have no personal love of computational linear algebra.

I will gladly make the necessary changes to ode-initval if such an interface will become available and if I can spare the time for it. Until then, I think I will continue the ODE-solver work with what is currently available in GSL. Hopefully linear algebra will get the much-needed interfaces! -- Tuomo.Keskitalo@iki.fi http://iki.fi/tuomo.keskitalo
