原文:https://www . geesforgeks . org/python-numpy-多项式-legline-method/

**np.legline()**法求一个勒让德级数其图形为直线。

语法: np.legline(off, scl) 参数: off,scl : 【标量】指定行由 off + scl*x 给出。

返回:【ndarray】结果行的勒让德级数系数数组。

代码#1 :

# Python program explaining 
# numpy.legline() method  

# importing numpy as np   
# and numpy.polynomial.legendre module as geek  
import numpy as np  
import numpy.polynomial.legendre as geek 

# using np.legline() method  
res = geek.legline(2, 3)  

# Resulting legendre series 
print (res)  

Output:

[2 3]

代码#2 :

# Python program explaining 
# numpy.legline() method  

# importing numpy as np   
# and numpy.polynomial.legendre module as geek  
import numpy as np  
import numpy.polynomial.legendre as geek 

# using np.legline() method  
res = geek.legline(1, 4)  

# Resulting legendre series 
print (res)

Output:

[1 4]
