The SquareEuclidean type exposes the following members.

Methods

	Name	Description
	Distance(Double, Double)	Computes the distance d(x,y) between points x and y.
	Distance(Double, Double)	Computes the distance d(x,y) between points x and y.
	Distance(SparseDouble, SparseDouble)	Computes the distance d(x,y) between points x and y.
	Distance(Double, Double, Double, Double)	Gets the Square Euclidean distance between two points.
	Equals	Indicates whether this instance and a specified object are equal. (Inherited from ValueType.)
	GetHashCode	Returns the hash code for this instance. (Inherited from ValueType.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	Similarity(Double, Double)	Gets a similarity measure between two points.
	Similarity(Double, Double)	Gets a similarity measure between two points.
	Similarity(SparseDouble, SparseDouble)	Gets a similarity measure between two points.
	Sparse	Computes the distance d(x,y) between points x and y.
	ToString	Returns the fully qualified type name of this instance. (Inherited from ValueType.)

Extension Methods

	Name	Description
	HasMethod	Checks whether an object implements a method with the given name. (Defined by ExtensionMethods.)
	IsEqual	Compares two objects for equality, performing an elementwise comparison if the elements are vectors or matrices. (Defined by Matrix.)
	To(Type)	Overloaded. Converts an object into another type, irrespective of whether the conversion can be done at compile time or not. This can be used to convert generic types to numeric types during runtime. (Defined by ExtensionMethods.)
	ToT	Overloaded. Converts an object into another type, irrespective of whether the conversion can be done at compile time or not. This can be used to convert generic types to numeric types during runtime. (Defined by ExtensionMethods.)
