# Interpolation – What it is

For a given set of data points, interpolation can be defined as construction a polynomial which passes through every of these data points. Visually, interpolation can be interpreted as finding a curve that passes through all points on a graph.

# Lagrange Interpolation

There are many methods of interpolation, each having it’s own advantages and disadvantages. For this project, I’ve chosen to implement “Lagrange Interpolation”, which has already been juicily described here : http://en.wikipedia.org/wiki/Lagrange_polynomial

# Implementation details

This program demonstrates “Lagrange Interpolation” visually. Users select some points on a grid, and the program will draw a curve that passes through each and every of the selected points. Not only does this program interpolate the data points, it also extrapolates to estimate how points beyond the given data set will look like.

# Screenshots

Below shows a quick preview. Selected points are cyan in color. The white line shows the curve derived from interpolating the selected data points. Advertisements
