Python Numpy np.polygrid2d()用法及代碼示例

np.polygrid2d()方法用於評估x和y的笛卡爾積的二維多項式級數。

用法： np.polygrid2d(x, y, c)

參數：

x, y :[array_like]The two dimensional series is evaluated at the points in the Cartesian product of x and y. If x or y is a list or tuple, it is first converted to an ndarray, otherwise it is left unchanged and, if it isn’t an ndarray, it is treated as a scalar.

c :[array_like]arrays of coefficient polynomial series.

Return :[ndarray] The values of the two dimensional polynomial series at points in the Cartesian product of x and y.

代碼1：

# Python program explaining 
# numpy.polygrid2d() method  
  
# importing numpy as np 
  
import numpy as np  
from numpy.polynomial.polynomial import polygrid2d 
  
# Input polynomial series coefficients 
c = np.array([[1, 3, 5], [2, 4, 6]])  
  
# using np.polygrid2d() method  
ans = polygrid2d([7, 9], [8, 10], c) 
print(ans)

輸出：

[[ 3271.  5025.]
 [ 4107.  6309.]]

代碼2：
