给我一段matlab代码,用机器人绘制一个长方形

clear all
clc

% 创建机器人模型
L1 = Link([0, 0.15, 0.3, 0, 0], 'standard');
L2 = Link([0, 0, 0.3, 0, 0], 'standard');
L3 = Link([0, 0, 0.15, 0, 0], 'standard');
robot = SerialLink([L1 L2 L3], 'name', 'rectangle');

% 设置绘图参数
workspace = [-0.4 0.4 -0.4 0.4 -0.4 0.4];
scale = 0.1;
q = zeros(1,3);

% 绘制长方形
rectangle = [0 0; 0.2 0; 0.2 0.3; 0 0.3; 0 0];
for i = 1:5
x = rectangle(i,1);
y = rectangle(i,2);
q = robot.ikine(transl(x,y,0),'q0',q);
robot.plot(q,'workspace',workspace,'scale',scale);
pause(0.1);
end
q = robot.ikine(transl(0,0,0),'q0',q);
robot.plot(q,'workspace',workspace,'scale',scale);
