%四阶龙格库塔方法
function[T,U]=kutta(a,b,h,c)
%计算点的个数
n=round((b-a)/h)+1;
%定义T,U的维数
t=zeros(n,1);
u=zeros(n,1);
%微分方程的初始条件
t(1)=a;
u(1)=c;
%显示微分方程的初始条件

function [x,y] = MyRunge_Kutta(fun,x0,xt,y0,PointNum,varargin)
%Runge-Kutta 方法解微分方程形为 y’(t) = f(x,y(x))
%此程序可解高阶的微分方程。只要将其形式写为上述微分方程的向量形式
% x范围为[x0,xt],初值为 y0, PointNum为离散点数,varargin为可选输入项可传适当参数给函数
