Python| Numpy np.polygrid3d() 方法

np.polygrid3d()方法用于评估 x、y 和 z 的笛卡尔积上的 3-D 多项式序列。

代码#1:

# Python program explaining
# numpy.polygrid3d() method 
  
# importing numpy as np
  
import numpy as np 
from numpy.polynomial.polynomial import polygrid3d
  
# Input polynomial series coefficients
c = np.array([[1, 3, 5], [2, 4, 6], [10, 11, 12]]) 
  
# using np.polygrid3d() method 
ans = polygrid3d([7, 9], [8, 10], [5, 6], c)
print(ans)
输出:
[[ 416970.  491223.]
 [ 635850.  749079.]]

代码#2:
