# SquareEuclidean Structure

Square-Euclidean distance and similarity. Please note that this distance is not a metric as it doesn't obey the triangle inequality.

Syntax
```[SerializableAttribute]
public struct SquareEuclidean : IDistance<double[]>,
IDistance<double[], double[]>, ISimilarity<double[]>,
ISimilarity<double[], double[]>, IDistance<double>,
IDistance<double, double>, ISimilarity<double>,
ISimilarity<double, double>, IDistance<Sparse<double>>,
IDistance<Sparse<double>, Sparse<double>>,
ISimilarity<Sparse<double>>, ISimilarity<Sparse<double>, Sparse<double>>```

The SquareEuclidean type exposes the following members.

Methods
NameDescription
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.)
