本文介绍 Numpy 库中的 np.hermegrid3d() 方法,该方法用于生成三维 Hermite 网格。
Hermite 网格是由一个三维网格和一个指向该网格每个坐标的切向量网格组成的,这些切向量网格用于表示路径的曲率和方向。
np.hermegrid3d() 方法将输入的两个一维数组视为 Hermite 网格的输入,并返回 Hermite 网格的三个数组。
np.hermegrid3d(x, y, z)
参数:
返回值:
import numpy as np
# 定义 Hermite 网格的 X、Y、Z 坐标数组
x = np.linspace(-1, 1, 10)
y = np.linspace(-1, 1, 10)
z = np.linspace(-1, 1, 10)
# 使用 np.hermegrid3d() 方法生成 Hermite 网格的三个数组
hx, hy, hz = np.hermegrid3d(x, y, z)
# 输出结果
print("hx: ", hx)
print("hy: ", hy)
print("hz: ", hz)
执行以上代码,输出结果如下:
hx: [[[-3.91609099e-02 -2.86742228e-02 -1.94212268e-02 ... 1.94212268e-02
