np.legroots()
method is used to compute the roots of a legendre series.Return the roots of the polynomial.
Syntax :
np.legroots(c)
Parameters:
c :[array_like] 1-D arrays of legendre series coefficients.Return : [ndarray] Array of the roots of the series. If all the roots are real, then out is also real, otherwise it is complex.
Code #1 :
# Python program explaining # numpy.legroots() method # importing numpy as np # and numpy.polynomial.legendre module as geek import numpy as np
import numpy.polynomial.legendre as geek
# Input legendre series coefficients s = ( 2 , 4 , 8 )
# using np.legroots() method res = geek.legroots(s)
# Resulting legendre series coefficient print (res)
|
Output:
[-0.60762522 0.27429189]
Code #2 :
# Python program explaining # numpy.legroot() method # importing numpy as np # and numpy.polynomial.legendre module as geek import numpy as np
import numpy.polynomial.legendre as geek
# legendre series coefficients s = ( 1 , 2 , 3 , 4 , 5 )
# using np.legroots() method res = geek.legroots(s)
# Resulting legendre series print (res)
