Question

这是我的代码：

import numpy as np

cx = np.array([0, 0, 3, 3])
cy = np.array([0, 3, 4, 0])
M = len(cx)

for j in range(M):
    wx = 0
    wy = 0

    for i in range(M):
        if i == j:
            continue
        x = cx[i] - cx[j]
        y = cy[i] - cy[j]
        wx += -x / np.sqrt(x ** 2 + y ** 2)
        wy += -y / np.sqrt(x ** 2 + y ** 2)

Move = (
    wx / np.sqrt(wx ** 2 + wy ** 2),
    wy / np.sqrt(wx ** 2 + wy ** 2),
)

我的代码有什么问题？非常感谢您的帮助

Answer 2

尝试一下：

import numpy as np

cx = np.array([0, 0, 3, 3])
cy = np.array([0, 3, 4, 0])
M = len(cx)

for j in range(M):
    wx = 0
    wy = 0

    for i in range(M):
        if i == j:
            continue
        x = cx[i] - cx[j]
        y = cy[i] - cy[j]
        wx += -x / np.sqrt(x ** 2 + y ** 2)
        wy += -y / np.sqrt(x ** 2 + y ** 2)

    Move = (
        wx / np.sqrt(wx ** 2 + wy ** 2),
        wy / np.sqrt(wx ** 2 + wy ** 2),
    )

    print(Move)

我的程序只计算最后一个值
