% adfig15 -- Adapt Figure 15: AutoSpline: Periodic Thin-Plate spline Reconstructions
%    with automatic choice of penalty parameter;
%
%
% Here we depict a reconstruction using penalized smoothing splines,
% in which periodic thin-plate splines are used to smooth the data,
% with roughness penalty proportional to the energy stored in the
% second derivative.  The constant of proportionality (or Lagrangian
% tuning parameter) is the empirical minimizer of the Stein Unbiased
% Estimate of Risk.
