Python Numpy np.lagpow()用法及代码示例

np.lagpow()方法用于将Laguerre级数提高到给定的幂。它返回Laguerre级数 c提升权力战俘

用法： np.lagpow(c, pow, maxpower=16)

参数：

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

pow  :[integer] Power to which the series will be raised.

maxpower  :[integer, optional] Maximum allowed power.Default is 16.

返回：[ndarray] Laguerre系列的力量。

代码1：

# Python program explaining 
# numpy.lagpow() 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 
  
s = (2, 4, 8)  
     
# using np.lagpow() method  
res = geek.lagpow(s, pow = 3)  
  
# Resulting laguerre series coefficient 
print (res)

输出：

[   3176.  -25680.  100512. -206592.  246528. -161280.   46080.]
