根据提供的引用内容,无法直接回答矩阵链乘法代码的问题。但是,我们可以通过注释来提高代码的可读性和可维护性,从而更好地编写矩阵链乘法代码。以下是一个简单的矩阵链乘法代码的例子,其中包含了注释:
```python
def matrix_chain_order(p):
"""
矩阵链乘法
:param p: 矩阵维度列表
:return: 最小乘法次数和最优解
"""
n = len(p) - 1
m = [[0] * n for i in range(n)]
s = [[0] * n for i in range(n)]
for l in range(2, n + 1):
for i in range(n - l + 2):
j = i + l - 1
m[i][j] = float('inf')
for k in range(i, j):
q = m[i][k] + m[k + 1][j] + p[i] * p[k + 1] * p[j + 1]
if q < m[i][j]:
m[i][j] = q
s[i][j] = k
return m[0][n - 1], s
# 示例
p = [30, 35, 15, 5, 10, 20, 25]
print(matrix_chain_order(p))
```
