In numerical analysis, the Lagrange interpolating polynomial is the unique polynomial of lowest degree that interpolates a given set of data. Given a data set of coordinate pairs with 0 ≤ j ≤ k , the x j are called nodes and the y j are called values. The Lagrange polynomial L has degree ≤ k and assumes each value at the corresponding node, L = y j . Although named after Joseph-Louis Lagrange, who published it in 1795, the method was first discovered in 1779 by Edward Waring. It is also an easy
