np.lagpow() method is used to raise a Laguerre series to a given power.It returns the Laguerre series c raised to the power pow.

Syntax : np.lagpow(c, pow, maxpower=16)
Parameters:
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.

Return : [ndarray] Laguerre series of power.

Code #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) 


Output:

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