Methods

	Name	Description
	CityBlockDistance	Compute the city-block (Manhattan) distance between two data sets (1 norm).
	EuclideanDistance	Computes the Euclidean distance between two data sets (2 norm).
	MaximumDistance	Computes the maximum (Chebychev) distance between two data sets.
	PowerFunction	Power distance function. Encapsulates GetDistance() on a newly constructed Distance.PowerDistance object as a Distance.Function delegate.
	SquaredEuclideanDistance	Computes the squared Euclidean distance between two data sets.

Fields

	Name	Description
	CityBlockFunction	City-block (Manhattan) distance function. Encapsulates Distance.CityBlockDistance as a Distance.Function delegate.
	EuclideanFunction	Euclidean distance function. Encapsulates Distance.EuclideanDistance as a Distance.Function delegate.
	MaximumFunction	Maximum (Chebychev) distance function. Encapsulates Distance.MaximumDistance as a Distance.Function delegate.
	SquaredEuclideanFunction	Squared Euclidean distance function. Encapsulates Distance.SquaredEuclideanDistance as a Distance.Function delegate.

Remarks

Instances of delegate type Distance.Function are used by class ClusterAnalysis to compute the distances between singleton objects. Delegates are provided as static variables for euclidean, squared euclidean, city-block (Manhattan), maximum (Chebychev), and power distance functions.
