Methods

	Name	Description
	Clone	Creates a new object that is a copy of the current instance.
	Distance	Computes the squared distance in input space between two points given in feature space. (Overrides KernelBaseTInputDistance(TInput, TInput).)
	Equals	Determines whether the specified object is equal to the current object. (Inherited from Object.)
	Function(Double)	Quadratic kernel function.
	Function(Double, Double)	Quadratic kernel function. (Overrides KernelBaseTInputFunction(TInput, TInput).)
	GetHashCode	Serves as the default hash function. (Inherited from Object.)
	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 a string that represents the current object. (Inherited from Object.)
	Transform(Double)	Projects an input point into feature space.
	Transform(Double)	Projects a set of input points into feature space.
	Transform(Double, 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.)
