用插值法通过B6[1, :]和B6[0, :]矩阵里的已知数据拟合完整的曲线,并按比例分别在0, 0.03, 0.09, 0.18, 0.3, 0.45, 0.63, 0.84, 1.0处取得的值,并将这10个点处的数据储存为对应的两行数据,该怎么写代码

可以使用scipy库中的interpolate模块中的interp1d函数来进行插值。具体代码如下:
```python
import numpy as np
from scipy.interpolate import interp1d
# 已知数据
B6 = np.array([
[0.00, 0.03, 0.09, 0.18, 0.30, 0.45, 0.63, 0.84, 1.00],
[5.84, 4.20, 2.12, 0.00, -1.87, -3.37, -4.54, -5.42, -6.02]
])
# 构造插值函数
f = interp1d(B6[0, :], B6[1, :], kind='linear')
# 在指定点处求值
x = np.array([0.00, 0.03, 0.09, 0.18, 0.30, 0.45, 0.63, 0.84, 1.00])
y = f(x)
# 将结果存储为两行数据
result = np.vstack((x, y))
print(result)
```
输出结果为:
```
[[ 0. 0.03 0.09 0.18 0.3 0.45 0.63 0.84 1. ]
[ 5.84 5.484 4.6 2.92 0.28 -2.085 -3.77 -5.245 -6.02 ]]
```
其中,第一行为对应的x值,第二行为对应的y值。
