sine-cosine - Perl script to explore Math::RungeKutta
This script uses Math::RungeKutta to integrate the equations dy0/dt=y1 dy1/dt=-y0 from t=0 to t=2pi which of course should give one cycle of sine and cosine waves.
It uses Term::Clui to give you a choice of the various methods that Math::RungeKutta offers, and of a selection of timestep values or error criteria.
