public final class PolynomialCurveFitter
extends SimpleCurveFitter

Fits points to a polynomial function.
The size of the initial guess array defines the degree of the polynomial to be fitted. They must be sorted in increasing order of the polynomial's degree. The optimal values of the coefficients will be returned in the same order.

Since:

3.3

Method Detail

create

public static PolynomialCurveFitter create(int degree)

Creates a default curve fitter. Zero will be used as initial guess for the coefficients, and the maximum number of iterations of the optimization algorithm is set to Integer.MAX_VALUE.

Parameters:

degree - Degree of the polynomial to be fitted.

Returns:

a curve fitter.
