Cubic Spline Demo
(From Jimmy ball - http://www.mcsr.olemiss.edu/~ccjimmy/spline.html)
Below is an applet (Beta) demonstrating the approximating capabilities
of the Natural Cubic Spline Algorithm.
The red line represents the given function
1.0
(x0.3sqrt(0.5x + 7))
Simply select any combination of x values and hit the button labelled "Fit
it!". The applet calculates the spline interpolant from the (x,f(x)) pairs
and plots the result.
