Help with ODE's
Mon Apr 29 04:24:00 GMT 2002
i think gsl is a fantastic project, and i've been using it in my simulations
since i found out about it.
i have only ever had to solve 2 ODEs at one time, and i was lucky enough that
the example in the documentation deals with this scenario, however i find the
API of the ODE part of the library to be somewhat cryptic and i am having
problems changing my code to solve for 3 ODEs at one time.. could anyone
please give me some pointers as to how i would do that?
and also, i noticed that to do an 8th order runge-kutta i must declare a
jacobian, could somebody please explain to me how i get this from my
equations? i am aware of jacobians in mathematics, but never heard of it in
numerics, i must admit i am of an analytic background.
thanks in advance!
