注释
需要 Matplotlib。
示例
>>> import numpy as np >>> import matplotlib.pyplot as plt >>> from scipy.spatial import ConvexHull, convex_hull_plot_2d
随机点集的凸包
>>> rng = np.random.default_rng() >>> points = rng.random((30, 2)) >>> hull = ConvexHull(points)
绘制它
>>> _ = convex_hull_plot_2d(hull) >>> plt.show()
