Python | Numpy np.lagmul() method Last Updated : 29 Dec, 2019 Comments Improve Suggest changes Like Article Like Report np.lagmul() method is used to multiply one Laguerre series to another.It returns the product of two Laguerre series c1 * c2. Syntax : np.lagmul(c1, c2) Parameters: c1, c2 :[ array_like ] 1-D arrays of Laguerre series coefficients ordered from low to high. Return : [ndarray] Laguerre series coefficients representing their product.
