# Linear Program Polynomial Interpolation Calculator

Since the complexity of the calculations increases with the number of points, the program is limited to 25 coordinates (with distinct x-values in the set Q).

I'm trying to write a cubic spline interpolation program. I have written the program but, the graph is not coming out correctly. The spline uses natural boundary conditions(second dervative at start/end node are 0). I wrote a cubic spline package in Mathematica a long time ago.

Download Dreambox Control Center. Here is my translation of that package into Matlab. Note I haven't looked at cubic splines in about 7 years, so I'm basing this off my own documentation. You should check everything I say. The basic problem is we are given n data points (x(1), y(1))., (x(n), y(n)) and we wish to calculate a piecewise cubic interpolant. The interpolant is defined as S(x) = { Sk(x) when x(k) >cubic_driver(5) >>clf >>cubic_driver(10) >>clf >>cubic_driver(20) By the time you have twenty nodes your interpolant is visually indistinguishable from the Runge function.

Online Regression Tools, Polynomial Regression. In the case that the selected degree is one less than the number of data points a polynomial interpolation results. • Copy & Paste: You can copy and paste. The exponent can be indicated by preceding it by the character E or e, as you can see in the example.

Some comments on the Matlab code: I don't use any for or while loops. I am able to vectorize all operations. I quickly form the sparse tridiagonal matrix with spdiags. I solve it using the backslash operator. I counting on Tim Davis's UMFPACK to handle the decomposition and forward and backward solves. Hope that helps.

The code is available as a gist on github.
