Returns

Type	Description
System.Double	A double-precision value representing the distance d(x,y) between x and y according to the distance function implemented by this class.

Similarity(Double[], Double[])

Gets a similarity measure between two points.

Declaration

public double Similarity(double[] x, double[] y)

Parameters

Type	Name	Description
System.Double[]	x	The first point to be compared.
System.Double[]	y	The second point to be compared.
