Explicit methods based on a class of four stage fourth order Runge–Kutta methods for preserving quadratic laws. Let us consider a 4-stage explicit R–K method given by the Butcher array Explicit 4-stage 4th-order Runge–Kutta methods. The formulas describing Runge-Kutta methods look the same as those of the collocation methods of the previous chapter, but are abstracted away from the ideas of quadrature and collocation. In particular, the “quadrature nodes” need no longer be distinct and collocation conditions need not hold at each stage. 8.1 The Family of Runge-Kutta
