- function yhat=lfsmooth(varargin)
- %
- % a simple interface to locfit.
- % output is a vector of smoothed values, at each data point.
- % all locfit options, except evaluation structures, are valid.
- %
- % Example, to smooth a time series of observations,
- %
- % t = (1:100)';
- % y = 2*sin(t/10) + normrnd(0,1,100,1);
- % plot(t,y,'.');
- % hold on;
- % plot(t,lfsmooth(t,y,'nn',0.5));
- % hold off;
- %
- % Minimal input validation
- if nargin < 1
- error( 'At least one input argument required' );
- end
