问题描述

大家好,

我需要通过Runge-Kutta-Fehlberg方法求解常微分方程组(ODE)。我知道该算法仅使用ODE,其具有形式为y'= f(x,y)的函数。现在我想用ODE系统增强这个算法,[y1',y2',...,yn'] = [f1(x,y1,y2,... yn),f2(x,y1,y2) ,... yn),...,fn(x,y1,y2,... yn)]



怎么做?希望你支持我。谢谢。



我尝试了什么:



我试过这个用于ODE求解的算法。但不知道如何将其应用于ODE系统。

Hi everybody,
I need to solve a System of Ordinary Differential Equations (ODE) by Runge-Kutta-Fehlberg method. I know that algorithm only uses with an ODE which has a function with form y'=f(x,y). Now I want to enhance this algorithm with a system of ODE, [y1',y2',...,yn']=[f1(x,y1,y2,...yn),f2(x,y1,y2,...yn),...,fn(x,y1,y2,...yn)]

How to do this? Hope you support it to me. Thanks.

What I have tried:

I tried with this algorithm for an ODE solving. But not know how to apply it for a System of ODE.
