Question

MATLAB 画一个矩形随轨迹运动的动态图，并保留之前每个时刻的矩形框痕迹，大虾帮帮忙

Answer 1

抱歉之前赶着吃饭没看清题目

clc

clear all

close all

x1=0:0.1:2;

y2=1.5:-0.1:0;

x3=2:-0.1:0;

y4=0:0.1:1.5;

y1=1.5*ones(1,length(x1));

x2=2*ones(1,length(y2));

y3=zeros(1,length(x3));

x4=zeros(1,length(y4));

traj_x = -10:0.5:10;

traj_y = traj_x.^2;

x=zeros(length(traj_x),length([x1,x2,x3,x4]));

y=zeros(length(traj_x),length([y1,y2,y3,y4]));

x=traj_x'*ones(1,length([x1,x2,x3,x4]))+ones(length(traj_x),1)*[x1,x2,x3,x4];

y=traj_y'*ones(1,length([y1,y2,y3,y4]))+ones(length(traj_y),1)*[y1,y2,y3,y4];

plot(traj_x,traj_y,'--');%画轨迹如果不需要删掉即可

for i = 1: length(traj_x)

hold on

plot(x(i,:),y(i,:));

axis([-11,15,-0.5,110]);

pause(0.1);

end
