Method Detail

polar

public static LinePolar2D_F64 polar(java.util.List<Point2D_F64> points,
                                    LinePolar2D_F64 ret)

Computes the unweighted best fit line to the set of points using the polar line equation. The solution is optimal in the Euclidean sense, see [1] for more details.

Parameters:

points - Set of points on the line.

ret - Storage for the line. If null a new line will be declared.

Returns:

Best fit line

Parameters:

points - Set of points on the line.

weights - Weight for each point. weights[i] ≥ 0

ret - Storage for the line. If null a new line will be declared.

Returns:

Best fit line. or null if sum of weights is zero
