Python Numpy np.leggrid2d()用法及代码示例

np.leggrid2d()方法用于评估x和y的笛卡尔积的二维Legendre级数。

用法： np.leggrid2d(x, y, c)

参数：

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] 1-D arrays of legendre series coefficients ordered from low to high.

返回：[ndarray]二维Legendre系列在x和y的笛卡尔积上的点的值。

代码1：

# Python program explaining 
# numpy.leggrid2d() method  
  
# importing numpy as np 
  
import numpy as np  
from numpy.polynomial.legendre import leggrid2d 
  
# Input legendre series coefficients 
c = np.array([[1, 3, 5], [2, 4, 6]])  
  
# using np.leggrid2d() method  
ans = leggrid2d([7, 9], [8, 10], c) 
print(ans)

输出：

[[ 4751.5  7351.5]
 [ 5965.5  9229.5]]

代码2：

# Python program explaining 
# numpy.leggrid2d() method  
  
# importing numpy as np  
import numpy as np  
from numpy.polynomial.legendre import leggrid2d 
  
# Input legendre series coefficients 
c = np.array([[1, 3, 5], [2, 4, 6]])  
  
# using np.leggrid2d() method  
ans = leggrid2d(7, 8, c) 
  
print(ans)

输出：

4751.5
