I am currently working on implementing the numerical method RKF45 (Runge-Kutta-Fehlberg-45) with adaptive step size into python 3 and I believe I am running into a fundamental loop issue that I cannot resolve. Note, the portion of this numerical method I am having trouble implementing is the adaptive step siz…

How can I stop my Runge-Kutta2 (Heun) method from exploding?
I am currently trying to write some python code to solve an arbitrary system of first order ODEs, using a general explicit Runge-Kutta method defined by the values alpha, gamma (both vectors of dimension m) and beta (lower triangular matrix of dimension m x m) of the Butcher table which are passed in by the u…
