Using the Adams-Bashforth-Moulton method (via Runge-Kutta 4th order) to approximate the Lorenz problem.

The Runge Kutta method of 4th order works with a higher degree of accuracy than the common Euler method and with a fixed step rate as a five stage process, more precisely. and . with .

I am trying to develop a Matlab function for the 4th Order Runge-Kutta Method. It needs to be able to work with any function for given initial conditions, step size, etc. and then plot the results afterwards.

I want to make the code such that it can accept many initial conditions input as a vector and solve for each of them and store all the results in a matrix. Diagonally Implicit Runge–Kutta methods. Diagonally Implicit Runge–Kutta (DIRK) formulae have been widely used for the numerical solution of stiff initial value problems. The simplest method from this class is the order 2 implicit midpoint method. Kraaijevanger and Spijker's two-stage Diagonally Implicit Runge–Kutta method: Fjärde ordningens Runge–Kutta.

av A Rindstedt · 2016 — We construct a fourth order modified equation method for time discretization of second order equations, and rudimentarily test it against fourth order Runge Kutta 

The general Runge-Kutta algorithm is one of a few algorithms for solving first order ordinary differential equations. Below is a specific implementation for solving equations of motion and other second order ODEs for physics simulations, amongst other things. I created a code that solves differential equations using 4th order runge-kutta method.
