sgolay

This function computes the filter coefficients for all Savitzsky-Golay smoothing filters.

Calling Sequence

F = sgolay (p, n)
F = sgolay (p, n, m)
F = sgolay (p, n, m, ts)

Parameters

p:

polynomial

n:

odd integer value, larger than polynomial p

m:

positive integer less than 2^31 or logical

ts:

real or complex value

Description

This is an Octave function. 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.

Examples

y = sgolay(1,3,0)
y =
0.83333   0.33333  -0.16667
0.33333   0.33333   0.33333
-0.16667   0.33333   0.83333
