WhittakerHendersonSmootherSmoothLikeSavitzkyGolay Method

Smooths the data in a way comparable to a traditional Savitzky-Golay filter with the given parameters degree and m.

Namespace: Altaxo.Calc.Regression
Assembly: AltaxoCore (in AltaxoCore.dll) Version: 4.8.3448.0 (4.8.3448.0)
Syntax
C#
Copy
public static double[] SmoothLikeSavitzkyGolay(
	double[] data,
	int degree,
	int m
)

Parameters

data  Double
The input data.
degree  Int32
The degree of the polynomial fit used in the SG filter.
m  Int32
The half-width of the SG kernel. The kernel size of the SG filter (i.e. the number of points for fitting the polynomial) is 2*m + 1. Note that very strong smoothing will lead to numerical noise; recommended limits for m are 700, 190, 100, and 75 for Savitzky-Golay degrees 2, 4, 6, and 8, respectively.

Return Value

Double
The smoothed data.
