Python| Numpy 多项式 lagline() 方法

np.lagline()方法用于查找图形为直线的拉盖尔级数。

Syntax : np.lagline(off, scl)
Parameters:
off, scl :[scalar] The specified line is given by off + scl*x.

Return : [ndarray] Laguerre series coefficient array for the resulting line.

代码#1：

# Python program explaining 
# numpy.lagline() method  
      
# importing numpy as np   
# and numpy.polynomial.laguerre module as geek  
import numpy as np  
import numpy.polynomial.laguerre as geek 
      
# using np.lagline() method  
res = geek.lagline(2, 3)  
    
# Resulting Laguerre series 
print (res)  

输出：

[ 5 -3]

代码#2：

# Python program explaining 
# numpy.lagline() method  
      
# importing numpy as np   
# and numpy.polynomial.laguerre module as geek  
import numpy as np  
import numpy.polynomial.laguerre as geek 
      
  
# using np.lagline() method  
res = geek.lagline(1, 4)  
    
# Resulting laguerre series 
print (res)

输出：

[ 5 -4]
