MATLAB中可以用命令subplot绘制心形线和摆线。首先,我们可以使用theta=linspace(0,2*pi,1000)生成从0到2π的1000个均匀间隔的角度值。然后,可以使用以下公式计算心形线的x和y坐标:
x = 16*sin(theta).^3;
y = 13*cos(theta) - 5*cos(2*theta) - 2*cos(3*theta) - cos(4*theta);
最后,使用subplot命令将两个图形绘制在同一平面的两个窗口中。第一个窗口绘制心形线,第二个窗口绘制摆线。
具体的MATLAB代码如下:
theta = linspace(0,2*pi,1000);
x_heart = 16*sin(theta).^3;
y_heart = 13*cos(theta) - 5*cos(2*theta) - 2*cos(3*theta) - cos(4*theta);
x_cycloid = 8*(1-cos(theta));
y_cycloid = 8*(theta-sin(theta));
subplot(1,2,1);
plot(x_heart,y_heart);
title('心形线');
subplot(1,2,2);
plot(x_cycloid,y_cycloid);
title('摆线');<span class="em">1</span><span class="em">2</span><span class="em">3</span>
