Cubic Spline and Lagrange Interpolation Demo

Interpolation using Cubic Splines

Interpolation using Lagrange polynomials

Note: This and the related demos were written some time ago by then-student Mark Hoefer. For mathematical background, see course handouts on Lagrange interpolation , cubic Bezier curves , cubic spline curves , and nonuniform splines . (A couple of diagrams are not included, as they were physically pasted into the handouts.)
