Method Details

estimate

public Polynomial estimate(double[] x,
 double[] y)
                    throws InterpolationException

Estimates polynomial from provided x and y points.

Parameters:

x - x points the estimated polynomial passes through.

y - y points the estimated polynomial passes through.

Returns:

estimated polynomial.

Throws:

IllegalArgumentException - if any of the provided values doesn't have the same length.

InterpolationException - if interpolation fails for numerical reasons.

estimateCoefficients

public double[] estimateCoefficients(double[] x,
 double[] y)
                              throws InterpolationException

Estimates polynomial coefficients from provided x and y points.

Parameters:

x - x points the estimated polynomial passes through.

y - y points the estimated polynomial passes through.

Returns:

coefficients of estimated polynomial.

Throws:

IllegalArgumentException - if any of the provided values doesn't have the same length.
