Formulation of Runge–Kutta methods In carrying out a step we evaluate s stage values Y1, Y2,, Ys and s stage derivatives F1, F2, , Fs, using the formula Fi = f(Yi). Each Yi is deﬁned as a linear combination of the Fj added on to y0: Yi = y0 +h Xs j=1 aijFj, i = 1,2,,s, and the approximation at x1 = x0 +h is found from y1 = y0 +h Xs i=1 biFi.

Just like Euler method and Midpoint method, the Runge-Kutta method is a numerical method that starts from an initial point and then takes a short step forward to find the next solution point. The formula to compute the next point is where h is step size and The local truncation error of RK4 is of order, giving a global truncation error of order.

Runge-Kutta method You are encouraged to solve this task according to the task description, using any language you may know. In this video, Runge Kutta method f order 2 to solve Differential Equations has been described in an easy to understand manner.If you have any queries or sug Trapezoidal Method trapz performs numerical integration via the trapezoidal method. This method approximates the integration over an interval by breaking the area down into trapezoids with more easily computable areas. The trapezoidal method, which has already been described, is a simple example of both a Runge–Kutta method and a predictor–corrector method with a truncation error of order h3. The predictor–corrector methods we consider now have much smaller truncation errors. As an initial example we consider the Adams–Bashforth–Moulton method.

2.1 Numerical Methods to Simulate Chaotic Oscillators. There exists numerical methods that depend of one-step or multisteps to provide a solution, and also some of them can change the order and the step size. In this work, we use three well-known methods, namely, Forward-Euler, Trapezoidal, and fourth-order Runge-Kutta.
