LinearFitBySvd(IROMatrixDouble, Double, Double, Int32, Int32, Double) Constructor

public LinearFitBySvd(
	IROMatrix<double> xbase,
	double[] yarr,
	double[]? stddev,
	int numberOfData,
	int numberOfParameter,
	double threshold
)

Parameters

xbase  IROMatrixDouble

The matrix of x base values of the data set. Dimensions: numberOfData x numberOfParameters. The matrix is changed during the calculation.

yarr  Double

The array of y values of the data set.

stddev  Double

The array of y standard deviations of the data set. Can be if the standard deviations are unknown.

numberOfData  Int32

The number of data points (may be smaller than the array sizes of the data arrays).

numberOfParameter  Int32

The number of parameters to fit (equals the number of columns of xbase).

threshold  Double

A threshold value (usually 1E-5) used to discard unimportant singular values.
