谢尔平斯基地毯是一种分形图形,其维数为1.585。下面是一个简单的 Python 代码实现:
```python
import numpy as np
import matplotlib.pyplot as plt
def sierpinski_carpet(n):
if n == 0:
return np.array([[1]])
else:
prev_carpet = sierpinski_carpet(n-1)
prev_size = prev_carpet.shape[0]
new_size = 3 * prev_size
new_carpet = np.zeros((new_size, new_size))
for i in range(3):
for j in range(3):
if i == 1 and j == 1:
new_carpet[prev_size:2*prev_size, prev_size:2*prev_size] = prev_carpet
else:
new_carpet[i*prev_size:(i+1)*prev_size, j*prev_size:(j+1)*prev_size] = prev_carpet
return new_carpet
carpet = sierpinski_carpet(4)
plt.imshow(carpet, cmap='gray')
plt.axis('off')
plt.show()
```
这个代码使用递归的方式生成谢尔平斯基地毯,最终输出一个 numpy 数组,可以使用 matplotlib 库将其可视化。
