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.
