np.lagroots() method is used to compute the roots of a Laguerre series.Return the roots of the polynomial.
Syntax :
np.lagroots(c)
Parameters:
c :[array_like] 1-D arrays of Laguerre series coefficients ordered from low to high.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.lagroots() 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.lagroots() method res = geek.lagroots(s) # Resulting laguerre series coefficient print (res) |
Output:
