Methods

	Name	Description
	Distance	Computes the distance d(x,y) between points x and y. (Inherited from IDistanceT, U.)

Remarks

The framework distinguishes between metrics and distances by using different types for them. This makes it possible to let the compiler figure out logic problems such as the specification of a non-metric for a method that requires a proper metric (i.e. that respects the triangle inequality).

The objective of this technique is to make it harder to make some mistakes. However, it is generally possible to bypass this mechanism by using named constructors available at each of the classes, such as Minkowski's Nonmetric(Double) method, to create distances implementing the IMetricT interface that are not really metrics. Use at your own risk.
