See Butcher: A History of the Runge-Kutta method. In summary, people (Nystroem, Runge, Heun, Kutta,) at the end of the 19th century experimented with success in generalizing the methods of numerical integration of functions in one variable $$\int_a^bf(x)dx,$$ like the Gauss, trapezoidal, midpoint and Simpson methods, to the solution of differential equations, which have an integral form $$y(x)=y_0+\int_{x_0}^x f(s,y(s))\,ds.$$ Runge Kutta method gives a more stable results that euler method for ODEs, and i know that Runge kutta is quite complex in the iterations, encompassing an analysis of 4 slopes to approximate the 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.

This paper constitutes a centenary survey of Runge--Kutta methods. It reviews the second and third methods are different versions of the trapezoidal rule.

• ode23tb is an implementation of TR-BDF2, an implicit Runge-Kutta formula with a first stage that is a The trapezoidal rule is to find the exact value of a definite integral using a numerical method. This rule is mainly based on the Newton-Cotes formula which states that one can find the exact value of the integral as an nth order polynomial.

It samples the slope at intermediate points as well as the end points to find a good average of the slope across the interval.
