Python | Numpy np.leg2poly() method Last Updated : 29 Dec, 2019 Comments Improve Suggest changes Like Article Like Report 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.
