Owning Class: filter design

Requires: MathScript RT Module

Syntax

b = fir_sgsmooth(p, f, w)

b = fir_sgsmooth(p, f)

[b, d] = fir_sgsmooth(p, f, w)

[b, d] = fir_sgsmooth(p, f)

Legacy Name: sgolay

Description

Computes the coefficients of a Savitzky-Golay FIR smoothing filter.

Examples

Inputs

Name Description
p Specifies the order of the polynomial. p must be a positive integer.
f Specifies the number of points to use in fitting. f must be a positive odd integer.
w Specifies the weighting vector. w can be an empty vector or an real vector with length f.

Outputs

Name Description
b Returns the coefficients of the filter.
d Returns the differentiation filters. The i-th column of d is a differentiation filter for derivatives of order i-1.
