Syntax

public static LinearFitBySvd FitPolymomialDestructive(
	int order,
	double[] xValues,
	double[] yValues,
	double[]? errorValues,
	int count
)

order Int32: The order of the fit (1: linear, 2: quadratic, etc.).
xValues Double: The array of x-values. The values of the array are modified during evaluation.
yValues Double: The array of y-values.
errorValues Double: The array of error values. If , error values are set to 1 for each element.
count Int32: Number of values to use (array[0] ... array[count-1]).

LinearFitBySvd
The fitted model.

Remarks

Special measures are taken (scaling of the x-variable) in order to keep precision high.
