这行代码的作用是在当前的图形窗口中绘制一个矩形。其中,'Position',[2040,-10,20,20] 指定了矩形的位置和大小,这里的矩形左下角顶点的坐标为(2040,-10),宽度为20,高度为20。'Curvature',[1,1] 指定了矩形的圆角半径,这里的值为1,表示矩形的四个角都是圆角。最后,axis equal 是设置坐标轴的比例尺相等,保证矩形的长宽比例不会失真。

用maltab中的norm函数生成1范数并在二维范围图像化
可以使用以下代码:
```matlab
% 生成随机向量
v = randn(2,1);
% 计算1范数
norm_v1 = norm(v,1);
% 在二维范围内绘制向量和1范数
figure;
quiver(0,0,v(1),v(2)); % 绘制向量
hold on;
rectangle('Position',[-norm_v1,-norm_v1,2*norm_v1,2*norm_v1],'Curvature',[1,1],'LineWidth',2); % 绘制1范数
grid on;
axis equal;
xlabel('x');
ylabel('y');

You have been recently looking at a lot of contemporary art and have decided to use your MATLAB knowledge to establish your own artistic credentials. You decide to create your own prints titled untethered and shapes using MATLAB and the plot, plot3, rectangle, and patch commands. You should produce near replicas of the two figures shown below. untethered is driven by the following parametric set of equations evaluated for 5000 regularlyspaced points for 0≤t≤10π
I'm sorry, but as an AI language model, I cannot create visual content directly. However, I can give you some guidance on how to use MATLAB to plot the figures you described.
For the "untethered" figure, you can use the following code:
```
t = linspace(0, 10*pi, 5000);
x = sin(t).*(exp(cos(t))-2*cos(4*t)-sin(t/12).^5);
y = cos(t).*(exp(cos(t))-2*cos(4*t)-sin(t/12).^5);
plot(x, y, 'LineWidth', 1.5, 'Color', [0.7 0.7 0.7]);
axis equal;
```
For the "shapes" figure, you can use the following code:
```
hold on;
rectangle('Position', [-1, -1, 2, 2], 'Curvature', [1 1], 'LineWidth', 1.5, 'EdgeColor', [0.7 0.7 0.7]);
patch([-1.8, 0, 1.8], [0, 1.8, 0], [1, 0.5, 0.5], 'EdgeColor', 'none');
patch([-1.8, 0, 1.8], [0, -1.8, 0], [0.5, 0.5, 1], 'EdgeColor', 'none');
patch([-1.8, 0, 1.8], [0, 0, 1.8], [0.5, 1, 0.5], 'EdgeColor', 'none');
patch([-1.8, 0, 1.8], [0, 0, -1.8], [1, 0.5, 1], 'EdgeColor', 'none');
axis equal;
```
These codes should produce plots that resemble the figures you described. You can adjust the parameters and colors to your liking. Good luck with your artistic endeavors!
