Python Numpy np.leggrid3d()方法
np.leggrid3d()方法用于评估x、y和z的笛卡尔乘积上的3-D legendre系列。
语法: np.leggrid3d(x, y, z, c)
参数:
x, y, z : [array_like]三维数列在x、y和z的笛卡尔乘积中的各点进行评估。如果x或y或z是一个列表或元组,它首先被转换为一个ndarray,否则它将保持不变,如果它不是一个ndarray,它被当作一个标量。
c : [array_like] legendre series coefficients.
返回: [ndarray] 在x和y的笛卡尔乘积中的各点的二维传奇数列的值。

# importing numpy as np
import numpy as np
from numpy.polynomial.legendre import leggrid3d
# Input legendre series coefficients
c = np.array([[1, 3, 5], [2, 4, 6], [10, 11, 12]])
# using np.leggrid3d() method
ans = leggrid3d([7, 9], [8, 10], [5, 6], c)
print(ans)
