Python Numpy np.lag2poly()用法及代碼示例

np.lag2poly()方法用於將Laguerre級數轉換為多項式。

用法： np.lag2poly(c)

參數：

c :[array_like] 1-D arrays of Laguerre series coefficients ordered from low to high.

返回：[ndarray]包含等效多項式係數的一維數組。

代碼1：

# Python program explaining 
# numpy.lag2poly() method  
    
# importing numpy as np   
# and numpy.polynomial.laguerre module as geek  
import numpy as np  
import numpy.polynomial.laguerre as geek 
    
# Input laguerre series coefficients 
  
c = np.array([0.1, 0.2, 0.3, 0.4, 0.5])  
     
# using np.lag2poly() method  
res = geek.lag2poly(c)  
  
# Resulting equivalent polynomial series coefficient 
print (res)

輸出：

[ 1.5        -4.          2.25       -0.4         0.02083333]

代碼2：

# Python program explaining 
# numpy.lag2poly() method  
    
# importing numpy as np   
# and numpy.polynomial.laguerre module as geek  
import numpy as np  
import numpy.polynomial.laguerre as geek 
    
# Input laguerre series coefficients 
  
c = ( 1, 2, 3, 4, 5) 
     
# using np.lag2poly() method  
res = geek.lag2poly(c)  
  
# Resulting equivalent polynomial series coefficient 
print (res)

輸出：

[ 15.         -40.          22.5         -4.           0.20833333]
