np.leg2poly()
method is used to convert a legendre series to a polynomial.
Syntax :
np.leg2poly(c)
Parameters:
c :[array_like] 1-D arrays of legendre series coefficients ordered from low to high.Return : [ndarray] 1-D array containing the coefficients of the equivalent polynomial.
Code #1 :
# Python program explaining # numpy.leg2poly() 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 c = np.array([ 0.1 , 0.2 , 0.3 , 0.4 , 0.5 ])
# using np.leg2poly() method res = geek.leg2poly(c)
# Resulting equivalent polynomial series coefficient print (res)
|
Output:
[ 0.1375 -0.4 -1.425 1. 2.1875]
Code #2 :
# Python program explaining # numpy.leg2poly() 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 c = ( 1 , 2 , 3 , 4 , 5 )
# using np.leg2poly() method res = geek.leg2poly(c)
# Resulting equivalent polynomial series coefficient print (res)

Output:
[ 1.375 -4. -14.25 10. 21.875]
