Polynomial interpolation

Common card · No. 289522

In numerical analysis, polynomial interpolation is the interpolation of a given data set by the polynomial of lowest possible degree that passes through the points in the dataset. Given a set of n + 1 data points ( x 0 , y 0 ) , … , ( x n , y n ) {\displaystyle (x_{0},y_{0}),\ldots ,(x_{n},y_{n})} , with no two x j {\displaystyle x_{j}} the same, a polynomial function p ( x ) = a 0 + a...
