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:
