np.lagfromroots()方法用於生成具有給定根的Laguerre級數。
用法:np.lagfromroots(roots)
參數:
roots :[array_like] Input sequence containing the roots.
返回:[ndarray] Laguerre級數的一維係數數組。
代碼1:
# Python program explaining 
# numpy.lagfromroots() method  
    
# importing numpy as np   
# and numpy.polynomial.laguerre module as geek  
import numpy as np  
import numpy.polynomial.laguerre as geek 
    
# Input roots 
  
roots = (2, 4, 8)  
     
# using np.lagfromroots() method  
res = geek.lagfromroots(roots)  
  
# Resulting laguerre series coefficient 
print (res) 
輸出:
[-30. -18. -10. -6.]
代碼2:
# Python program explaining 
# numpy.lagfromroots() method  
    
# importing numpy as np   
# and numpy.polynomial.laguerre module as geek  
import numpy as np  
import numpy.polynomial.laguerre as geek 
    
# Input roots 
s = (1, 2, 3, 4, 5)  
  
    
# using np.lagfromroots() method  
res = geek.lagfromroots(s)  
  
# Resulting laguerre series coefficient 
print (res) 
輸出:
[ -26. -64. 120. -270. 240. -120.]
