Python | Numpy np.legmul() method Last Updated : 31 Dec, 2019 Comments Improve Suggest changes Like Article Like Report np.legmul() method is used to multiply one Legendre series to another.It returns the product of two Legendre series c1 * c2. Syntax : np.legmul(c1, c2) Parameters: c1, c2 :[ array_like ] 1-D arrays of Legendre series coefficients ordered from low to high. Return : [ndarray] Legendre series coefficients representing their product.
