% adfig14 -- Adapt Figure 14: AutoTrunc: Fourier Truncated
%            Reconstructions from Noisy Data;
%
% Here we depict a reconstruction using truncated Fourier expansions,
% in which only the low-order fourier components of the noisy signal
% are retained in reconstruction. The cut-off point for reconstruction
% in the frequency domain is automatically chosen; it is the empirical 
% minimizer of the Stein Unbiased Estimate of Risk among truncation rules.
