Adaptive runge kutta fehlberg matlab

I am writing a Runga Kutta 4 algorithm in MATLAB. I would like to add adaptive step sizing to this algorithm. From what I've read it seems you calculate the value of the function for two step size. MATH Computational Assignment #2 Due on Thurday, March 13, TTH pm Wenqiang Feng 1. Runge-Kutta-Fehlberg Figure 5: The 4th RK method and RKF method for Problem (c) The 4th RK method and RKF method for Problem Adaptive Runge-Kutta Methods MATLAB . SEC RUNGE-KUTTA METHODS Runge-Kutta-Fehlberg Method (RKF45) One way to guarantee accuracy in the solution of an I.V.P. is to solve the problem twice using step sizes h and h/2 and compare answers at the mesh points corresponding to the larger step size.

I am writing a Runga Kutta 4 algorithm in MATLAB. I would like to add adaptive step sizing to this algorithm. From what I've read it seems you calculate the value of the function for two step size. Adaptive step size control and the Runge-Kutta-Fehlberg method The answer is, we will use adaptive step size control during the computation. The idea is to start with a moderate step.Runge-Kutta-Fehlberg Method (RKF45). One way to guarantee accuracy in the solution of an I.V.P. is to solve the problem twice using step sizes h and h/2 and. Usage: [w t] = rkf45(f,a,b,ya,h,rtol) % Runge-Kutta-Fehlberg order 4/order 5 embedded pair % % Input: % f - Matlab inline function f(t,y) % a,b - interval % ya. I want the Runge Kutta Fehlberg to do the same (hopefully more accurately . RKF45 method allows for an adaptive step size to be determined.
