Solve the ODE using the ode4?

Do you love a good drink, but have a tight budget? Learn how to?

ode45 is based on an explicit Runge-Kutta (4,5) formula, the Dormand-Prince pair. Advertisement Taking a shower should. Good morning, I am trying to numerically solve a system of ODEs from a research paper. It calculates two approximations: one fourth-order RK approximation and one fifth-order. macmulkin Solve the ODE using the ode45 function on the time interval [0 20] with initial values [2 0]. Using the example I gave in my post on the matlabFunction, when I pass this function through ode45, with some initial conditions, does ode45 read the derivative -s. If the two approximations are sufficiently close, it accepts the fourth order approximation and increases the stepsize slightly for the next step. [t,y,te,ye,ie] = ode45(odefun,tspan,y0,options) additionally finds where functions of (t,y), called event functions, are zero.
