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 :
import numpy as np
import numpy.polynomial.laguerre as geek
s = ( 2 , 4 , 8 )
res = geek.lagpow(s, pow = 3 )
print (res)
|
Output:
[ 3176. -25680. 100512. -206592. 246528. -161280. 46080.]
Code #2 :
import numpy as np
import numpy.polynomial.laguerre as geek
s = ( 1 , 2 , 3 , 4 , 5 )
res = geek.lagpow(s, pow = 4 )
print (res)
