Implements Lagrange polynomial interpolation and analyzes interpolation accuracy using Mean Squared Error (MSE). Tests optimal number of interpolation nodes for the ...

This repository contains a Python implementation of the Lagrange Interpolation method for estimating the value of a function at a given interpolating point based on a set of data points. The code ...

Abstract: A modification of the conventional Lagrange interpolator is proposed in this paper, that allows one to approximate a band-limited signal from its own nonuniform samples with high accuracy.
