Neville's algorithm

Neville's algorithm is a numerical method used for polynomial interpolation that allows you to compute the value of a polynomial at a specific point based on known values at various points. It is particularly useful because it enables the construction of the interpolating polynomial incrementally, offering a systematic way to refine the approximation as new points are added. The basic idea behind Neville's algorithm is to build a table of divided differences that represent the polynomial interpolation step-by-step.
