Functions
template<typename T >
xyzVector< T >	numeric::first_principal_component (utility::vector1< xyzVector< T > > const &coords)
	return the first principal component of the given set of points More...
template<typename T >
xyzMatrix< T >	numeric::principal_components (utility::vector1< xyzVector< T > > const &coords)
