Runge-Kutta

Hi,
is the Runge-Kutta method implemented in ROOT? I looked in the website but couldnt find it (though I did find Chebyshev).
Cheers…

Currently there are no methods for solving ordinarly differential equations in ROOT like the Runge-Kutta.
They exist for example in GSL, see

gnu.org/software/gsl/manual/ … tions.html

Eventually a C++ wrapper to them could be added in the MathMore library, if required,

Best Regards

Hi,
this might be a bit redundant but could you please give me a tip(s) on how to do this?

The idea is to have C++ objects wrapping corresponding GSL C struct and this can be used together with other C++ classes in ROOT.

You can look for example how are implemented in MathMore for other GSL methods, like numerical integration, root finders or interpolation.

See for example:

Examples to use GSL ODE systems are in the online GSL doc:

gnu.org/software/gsl/manual/ … grams.html
