# Runge-Kutta methods are a family of iterative methods used for solving ordinary differential equations in the setting of Initial Value problems (IVP) where we are given a differential equation \ (y' (t) = f (t,y (t))\) over a time interval \ ( [t_0,t_1]\) with a starting point \ (y (t_0) = y_0\). We note that Boundary Value Problems (BVP) are differential equations are different to IVP as there are conditions imposed at the boundaries/extremes of the independent variable.

Runge-Kutta methods are a specialization of one-step numerical methods. Essentially, what characterizes Runge-Kutta methods is that the error is of the form Ei =Chk E i = C h k Where C is a positive real constant, the number k is called the order of the method

These videos were created to accompany a university course, Numerical Methods for Engineers, taught Spring 2013. The text used in the course was "Numerical M Runge-Kutta method is a popular iteration method of approximating solution of ordinary differential equations. Developed around 1900 by German mathematicians C.Runge and M. W. Kutta, this method is applicable to both families of explicit and implicit functions. Runge-kutta method definition, a numerical method, involving successive approximations, used to solve differential equations.

### Runge-Kutta Methods To avoid the disadvantage of the Taylor series method, we can use Runge-Kutta methods. These are still one step methods, but they depend on estimates of the solution at diﬀerent points. They are written out so that they don’t look messy: Second Order Runge-Kutta Methods: k1 =∆tf(ti,yi) k2 =∆tf(ti +α∆t,yi +βk1

They came into their own in the 1960s after signi–cant work by Butcher, and since then have grown into probably the most widely-used numerical methods for solving IVPs. In this section, we will provide a general Runge-Kutta Method in MATLAB Numerical Methods Tutorial Compilation. The above C program for Runge Kutta 4 method and the RK4 method itself gives higher accuracy than the inconvenient Taylor’s series; the accuracy obtained agrees up to the term h^r, where r varies for different methods, and is defined as the order of that method. Implicit Runge-Kutta schemes¶ We have discussed that explicit Runge-Kutta schemes become quite complicated as the order of accuracy increases.
