Cubic Spline or Polynomial Interpolation:
-
Natural Cubic Splines & Polynomial Interpolation vs. 1.3
Cubic Spline Cubic Spline
Polynomial Polynomial:   degree polynomial approximation
Verbose

     

 
 Version: 1.3
Explanation: Select Cubic Spline or Polynomial interpolation or both. Enter points that need to be approximated with a polynomial. e.g. -2,1;-1.5,2;-1,2;-0.5,1.5;
0,1;0.5,1.5;1,2;1.5,3;2,5 and hit the Solve Interpolation button. 
The degree of the approximated polynomial can be set between 1..9.
Floating point in standard notation with e or E as exponent is OK. fx. 120 1.20e2 12E+1 1200E-1 all represent the same number 120.
Verbose print out details about the each iteration steps, if checked.
The Test button setup default points to approximate (for testing only)
Email: hve@hvks.com if you have any questions.
This version has been tested with both IE8, Chrome 2, Safari 4 and FireFox 3 browser.
