LOESS regression smoothing

LOESS performs a locally weighted regression fit to noisy data

You are now following this Submission

Function fLOESS performs LOESS (locally weighted non-parametric regression fitting using a 2nd order polynomial) smoothing to one dimensional data, without the Matlab Curve Fitting Toolbox. This might be considered a marginally better approach to LOWESS, which produces a locally weighted regression using a linear fit.
