Python 代码实现：计算 X∈[-2,-1]、Y∈[0.2,0.6] 范围两个趋势线最短距离

以下是使用 Python 语言计算两个趋势线在给定范围内最短距离的示例代码： ```python import numpy as np def distance(x1, y1, x2, y2): return np.sqrt((x2 - x1) 2 + (y2 - y1) 2) # 假设两个趋势线的方程为 y = a1*x + b1 和 y = a2*x + b2 a1 = 1 b1 = 0 a2 = 2 b2 = 1 min_distance = float('inf') for x in np.linspace(-2, -1, 100): # 在 X 范围内生成多个点 for y in np.linspace(0.2, 0.6, 100): # 在 Y 范围内生成多个点 dist = distance(x, a1*x + b1, x, a2*x + b2) if dist < min_distance: min_distance = dist print("最短距离为:", min_distance) ``` ######[AI问答 | 238点数解答 | 2025-04-18 12:54:49]
