File Information
Description	Savitzky-Golay smoothing and differentiation filter (i.e.,polynomial smoothing and differentiation filte, or least-squares smoothing and differentiation filter) calculated with the recursive properties of Gram polynomials. This reccursive procedure can avoid the inaccuracy due to singular or badly scaled matrix when using a matrix approach.
Acknowledgements	This submission has inspired the following: z-transform of 1D & 2D Savitzky-Golay Smoothing and Differentiation Filter
MATLAB release	MATLAB 6.5.1 (R13SP1)
