Choose an ODE Solver Ordinary Differential Equations. An ordinary differential equation (ODE) contains one or more derivatives of a dependent variable, y, with respect to a single independent variable, t, usually referred to as time.The notation used here for representing derivatives of y with respect to t is y ' for a first derivative, y ' ' for a second derivative, and so on.

Numerical Methods for ODE in MATLAB MATLAB has a number of tools for numerically solving ordinary differential equations. We will focus on one of its most rudimentary solvers, ode45, which implements a version of the Runge–Kutta 4th order algorithm. (This is essentially the Taylor method of order 4, though

The basic usage for MATLAB’s solver ode45 is ode45(function,domain,initial condition). That is, we use >>[x,y]=ode45(f,[0 .5],1) and MATLAB returns two column vectors, the first with values of x and the second with values of y. (The MATLAB output is fairly long, so I’ve omitted it here.) Since x and y are
