Detailed Description

template<typename real_type_>
class OpenTissue::interpolation::PolynomialInterpolator< real_type_ >

Polynomial Interpolator. This is an implementation of the algorithm, which is described in Numerical Recipes in C, pp. 108-110.

The original algorithm as it stands in the book have a small error regarding how it tracks its way through the tableau (try to watch what happens if you extrapolate on the right side, that is only want to pick D's). We have corrected this error in our implementation.
