Java code for solving ODE   Message List  
Reply | Forward Message #127 of 369 |
Hi All,
I'm hoping someone might be able to help me find a java class or
interface that solves for ordinary differential equations using the
RK4 integration algorithm. I know that the RK4 algorithm is a method
given in the JSci API, but I'm not sure how I would use it and how I
set up the parameters. I'm only a beginner with Java programming, so
any information on these topics would be great.
Cheers

What compiler error do you get? If it does not like the use of the inner class you can just use a normal class: class MyDyByDxFunction implements Mapping { ...

Thanks Mark, I did manage to get the rungeKutta method working with your new suggestions and my simple ODE worked. Cheers! The ODE that I'm trying to solve is...
