In this paper, we propose a functional fitting s-stage Runge-Kutta method which is based on the exact integration of the set of the linearly independent functions u i (t), (i = 1,. .. , s). The method is exact when the solution of the ODE can be expressed as the linear combination of u i (t), although the method has an error for general ODE. In this work we… (More)

A new type of variable coefficient Runge-Kutta-Nyström methods is proposed for solving the initial value problems of the special form y(t) = f(t, y(t)). The method is based on the exact integration of some given functions in order to solve the problem exactly when the solution is the linear combination of these functions. If this is not the case, the… (More)
