Runge-Kutta method is designed for solving differential equations ode performance function, he has ode23, ode45, ode23s, etc., using the Runge-Kutta algorithm. ode45 expressed using fourth-order, fifth-order runge-kutta single-step algorithm, truncation error is (Δx). Solve is Nonstiff (non-rigid) of ordinary differential equations. Numerical solution to solve the problem is the preferred method, if time did not result should be that rigid, for use ode23 to solve.
