Optimal polynomial fitting by Damien Garcia

Optimal polynomial fitting according to the Akaike's information criterion. (akaikes information c..., polynomial fitting)

polyfit3 by Antoni J. Canós

Fit polynomial to data, with new features as forced to zero coefficients and data weighting. (fitting, polynomial fitting, approximation)
