问题描述:
Matlab程序:错误在哪里
建立函数文件fun5.m
function dy=fun5(t,y)
dy=[(-5*sin(t)*(5*cos(t)-y(1))+5*cos(t)*(5*sin(t)-y(2)))*(5*cos(t)-y(1))./((5*cos(t)-y(1))^2+(5*sin(t)-y(2))^2),
(-5*sin(t)*(5*cos(t)-y(1))+5*cos(t)*(5*sin(t)-y(2)))*(5*sin(t)-y(2))./((5*cos(t)-y(1))^2+(5*sin(t)-y(2))^2)]
主程序:
clear,clc
close all
[t,y]=ode45('fun5',[0,100],[10,0]);
X=5*cos(t);
Y=5*sin(t);
figure(1)
plot(X,Y,'r.')
hold on
plot(y(:,1),y(:,2),'*')
