Hi,
I agree with you, other methods are better but the idea is that I want
to test the LuaJIT implementation with a simpler algorithm and if it
works I will implement later a better algorithm.
As you have seen I have discovered already a major problem with the
RK4 implementation that I wrote and I need to adopt a different
approach with dynamic code generation to specialize the code with the
dimension of the system.
