public class PolynomialCurveFitter extends AbstractCurveFitter
polynomial
function.
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.AbstractCurveFitter.TheoreticalValuesFunction| Modifier and Type | Method and Description |
