Runge–Kutta–Nyström methods are specialized Runge–Kutta methods that are optimized for second-order differential equations. [ 22 ] [ 23 ] A general Runge–Kutta–Nyström method for a second-order ODE system
The Runge–Kutta–Fehlberg method has two methods of orders 5 and 4; it is sometimes dubbed RKF45 . Its extended Butcher Tableau is: / / / / / / / / / / / / / / / / / / / / / / / / / / The first row of b coefficients gives the fifth-order accurate solution, and the second row has order four.
Numerical methods for solving first-order IVPs often fall into one of two large categories: [5] linear multistep methods, or Runge–Kutta methods.A further division can be realized by dividing methods into those that are explicit and those that are implicit.

In mathematics and computational science, the Euler method (also called the forward Euler method) is a first-order numerical procedure for solving ordinary differential equations (ODEs) with a given initial value. It is the most basic explicit method for numerical integration of ordinary differential equations and is the simplest Runge–Kutta ...
The symplectic Euler method is the first-order integrator ... for time-dependent electromagnetic fields can also be constructed using Runge-Kutta ...
An - -stage Runge-Kutta method first calculates auxiliary slopes , …, by evaluating 𝑓 at suitable points and then as a weighted average. In an explicit Runge-Kutta method, the auxiliary slopes k 1 , k 2 , k 3 , … {\displaystyle k_{1},k_{2},k_{3},\dotsc } are calculated directly one after the other; in an implicit method, they are ...
In mathematics and computational science, Heun's method may refer to the improved [1] or modified Euler's method (that is, the explicit trapezoidal rule [2]), or a similar two-stage Runge–Kutta method. It is named after Karl Heun and is a numerical procedure for solving ordinary differential equations (ODEs) with a given initial value.
