6-1 Polynomial Interpolation

This program demonstrates polynomial interpolation. Given n data points, it uses a divided difference table to generate and plot the unique polynomial interpolation function of degree n -1 through the points.

To run the demo:

  1. Click the mouse in the graph panel to set from 2 up to 10 data points.
  2. Click the Interpolate button to plot the interpolation function.
  3. You can add more data points and click the Interpolate button again.
  4. Click the Reset button to start over.

The original Java Applets do not run in modern browsers, but you can download the Java code and run it locally on your desktop. Check back for JavaScript and Python versions - coming soon!
