fir_sgsmooth (MathScript RT Module Function)
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.
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. |
Examples
p = 2;
f = 15;
b = fir_sgsmooth(p, f)
