Given values x, uses Lagrange interpolation to find F(x) and F'(x), where X and Y describe the function Y = F(X).
The syntax is similar to Matlab's interp1 function, except that the 4th input argument is the order of the polynomial used for interpolation.

I wrote this function to interpolate orbital positions of GPS satellites. Lagrange interpolation is well suited to this problem.
