numpy_class.7z
这段代码存在一些问题。首先,在函数中的第3行,应该将len(X)改为D,因为后面的代码中需要使用D来循环遍历X数组。其次,在第6行中,应该使用np.greater(X[i], a)来判断X[i]是否大于a,因为X是一个数组,不能直接与a进行比较。同理,在第8行和第10行中,应该使用np.less(X[i], a)和np.equal(i, 0)来判断X[i]是否小于a和是否为第一个元素。在第14行中,应该使用y_1而不是y-1计算Y。最后,在第15行中,应该将YD初始化为0,否则会出现未定义的变量错误。
下面是修改后的代码:
```python
import numpy as np
X = np.arange(1, 6)
D = len(X)
def get_Penalized_1(X, a, k, m):
Y = 0
U = 0
for i in range(D):
if np.greater(X[i], a):
u = k * np.power((X[i] - a), m)
elif np.less(X[i], a):
u = k * np.power((-X[i] + a), m)
else:
u = 0
U = U + u
y = 1 + (X[i] + 1) / 4
if np.equal(i, 0):
Y1 = 10 * np.power((np.sin(np.pi * y)), 2)
elif np.less_equal(i, D - 1):
Y = Y + np.power((y_1 - 1), 2) * (1 + 10 * np.power((np.sin(np.pi * y)), 2))
else:
YD = np.power((y - 1), 2)
y_1 = y
F = np.pi / D * (Y1 + Y + YD) + U
return F
get_Penalized_1 = np.frompyfunc(get_Penalized_1, 4, 1)
x = get_Penalized_1(X, 10, 100, 4)
print(x)
```
