Detailed Description

A natural cubic spline interpolation class.

The class builds a cubic spline interpolant with natural boundary conditions using the x_values and y_values passed into the constructor. For details on the algorithm see the GSL documentation on gsl_interp_cspline.

Here is an example how to use this class:

intrp::CubicSpline interpolant{x_values, y_values};
const double x_to_interpolate_to =
CHECK(interpolant(x_to_interpolate_to) ==
custom_approx_interior(function(x_to_interpolate_to)));
