https://jayemmcee.wordpress.com/interpolationNewton’s Divided Differences method creates a lower triangular matrix by using the Newton basis, allowing us to solve the triangle very quickly. (This again results in the same interpolation polynomial) A recursive solver can be applied to each row of the triangle, by recognizing the relationship of the divided differences in the equation below.

www.cs.usask.ca › ~spiteri › M211computed, the Newton polynomial can be e ciently evaluated using Horner’s method. Note also that Newton interpolation can be done incrementally; i.e., the interpolant can be createdas points are being added. So we t a straight line to two points, then add a point and t a quadratic to three points, then add a point and t a cubic to four points ...
