Methods

	Name	Description
	Clone	Creates a new object that is a copy of the current instance.
	Distance(Double, Double)	Computes the squared distance in feature space between two points given in input space.
	Distance(SparseDouble, SparseDouble)	Computes the squared distance in feature space between two points given in input space.
	Equals	Indicates whether this instance and a specified object are equal. (Inherited from ValueType.)
	Function(Double)	Polynomial kernel function.
	Function(Double, Double)	Polynomial kernel function.
	Function(SparseDouble, SparseDouble)	Polynomial kernel function.
	GetHashCode	Returns the hash code for this instance. (Inherited from ValueType.)
	GetType	Gets the Type of the current instance. (Inherited from Object.)
	ReverseDistance	Computes the distance in input space between two points given in feature space.
	ToString	Returns the fully qualified type name of this instance. (Inherited from ValueType.)
	Transform(Double)	Projects an input point into feature space.
	Transform(Double)	Projects a set of input points into feature space.
	Transform(Double, Int32, Double)	Projects an input point into feature space.

Extension Methods

	Name	Description
	Distance	Computes the kernel distance for a kernel function even if it doesn't implement the IDistance interface. Can be used to check the proper implementation of the distance function. (Defined by Tools.)
	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.)
