Functions
template<typename Type = real_t>
prec_t	absolute (Type a, Type b)
	Absolute distance between two values which have an ordering with respect to zero.

template<typename Vector >
prec_t	euclidean (const Vector &v1, const Vector &v2)
	Euclidean distance between vectors (any type with a size() method and [] operator).

unsigned int	hamming (const std::string &a, const std::string &b)
	Hamming distance between two strings, defined as the number of positions at which the corresponding characters are different.

Function Documentation

prec_t chebyshev::prec::distance::euclidean	(	const Vector &	v1,
		const Vector &	v2
	)

inline

Euclidean distance between vectors (any type with a size() method and [] operator).

If the size of the vectors is different, NaN is returned.
