The Savitzky-Golay filter is based on approximating the given data by a polynomial using the Least-Squares parameter estimation. This implementation contains a function SG_calc.m which calculated the filter coefficients and an example script for simple implementation. Asymmetrical and non-integer parameters are allowed.

The SG filter is suitable for direct calculation of any signal derivatives of an arbitrary order limited by the Signal-to-noise ration of the original signal and sampling.
