sgolay This function computes the filter coefficients for all Savitzsky-Golay smoothing filters. F = sgolay (p, n) F = sgolay (p, n, m) F = sgolay (p, n, m, ts) p: polynomial n: odd integer value, larger than polynomial p m: positive integer less than 2^31 or logical ts: real or complex value This function computes the filter coefficients for all Savitzsky-Golay smoothing filters of order p for length n (odd). m can be used in order to get directly the mth derivative; ts is a scaling factor.
