用于查找点和曲线之间最小距离的Python代码

import numpy as np
from scipy import optimize

def curve_function(x, a, b, c):
    return a * x**2 + b * x + c

def distance_function(x, y, a, b, c):
    return np.abs(y - curve_function(x, a, b, c))

initial_guess = [1, 1, 1]

x_points = np.array([1, 2, 3, 4, 5])
y_points = np.array([2, 4, 6, 8, 10])

result = optimize.minimize(lambda params: distance_function(x_points, y_points, *params), initial_guess)

min_distance = result.fun
curve_params = result.x
print("最小距离：", min_distance)
print("曲线参数：", curve_params)
