ODEs - runge kutta

["Sam Halliday" <plendily at hotmail dot com>]

hello,

i am currently trying to numerically solve the lane-emden equation, which is 
a 2nd order differential equation, and experience has shown that the 4th 
order runge kutta is the best way to solve this.

i was interrested in using the GSL for solving this problem, although the 
examples section for ODE's scared me too much... must i really define so 
much, (jacobians and so forth), is there not a way in which i can just send 
my function, parameter (which actually is the time) and time step length to 
a library and let it do all the work? does anyone have a simple example i 
can follow so that i can use this library for this task? teh one in the 
documenattion seems to be too crypic, and tries to do too much for my 
needs...

please respond to me at

thanks!

cheers,
Sam
