This video is about Neville's Method (Neville's Algorithm) for function interpolation, which is based on Lagrange interpolating polynomials and is pretty tricky. Neville's Method for Interpolation and Neville's Method examples are done. Neville's Method is broken down step by step and it is crucial to understand it by thinking of it as a weighted average
