Remarks
The clamped cubic spline is a cubic spline where the derivative of the
interpolating function is specified at the left and right endpoints.
Evaluating x-values outside the range of tabulated values uses the last fitted cubic, or a linear extrapolation in the case of only 2 or 3 tabulated values.
