Introduction Matlab offers several approaches for solving initial value ordinary differential equations Runge-Kutta solutions are common (ode45, ode15s, etc.) Simulink is a Matlab add-on that allows one to simulate a variety of engineering systems If a model has no states or only discrete states, Simulink an implicit Runge-Kutta formula with two stages. The first stage is a trapezoidal rule step while the second stage uses a backward differentiation formula of order 2.

The Runge--Kutta--Fehlberg method (denoted RKF45) or Fehlberg method was developed by the German mathematician Erwin Fehlberg (1911--1990) in 1969 NASA report. The novelty of Fehlberg's method is that it is an embedded method from the Runge-Kutta family, and it has a procedure to determine if the proper step size h is being used.

In this tutorial, I explain how to solve a system of two nonlinear ordinary differential equations using the RK4th order method in MATLAB. This tutorial covers: MATLAB functions RK4 formula Carl Runge lived from 1856 until 1927. We know his name because he was the first to write about what we now call the Runge-Kutta method for the numerical solution of ordinary differential equations. His paper was published in 1895. Martin Kutta came along six years later. But Runge made many other contributions, including the subject of today's
