LinearFitBySvdFitPolymomialDestructive Method

Fits data provided as xcolumn and ycolumn with a polynomial base. Here special measures are taken (scaling of the x-variable) in order to keep the precision high.

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

Parameters

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 destroyed (altered) during the evaluation!
yValues  Double
The array of y-values.
errorValues  Double
The column of errorValues. If null, errorValues are set to 1 for each element.
count  Int32
Number of values to use (array[0] ... array[count-1].

Return Value

LinearFitBySvd
The fit.
