Namespaces
	xerus
	The main namespace of xerus.
	xerus::misc
	Collection of classes and functions that provide elementary functionality that is not special to xerus as a tensor library.

Functions
template<typename T >
void	xerus::misc::add (T *const __restrict _x, const T *const __restrict _y, const size_t _n) noexcept
	Adds _n entries of _y to the ones of _x. I.e. x += y. More...
template<typename T >
void	xerus::misc::add_scaled (T *const __restrict _x, const T _alpha, const T *const __restrict _y, const size_t _n) noexcept
	Adds _n entries of _y, scaled by _alpha to the ones of _x. I.e. x += alpha*y. More...
template<typename T , typename std::enable_if< std::is_trivial< T >::value, int >::type = 0>
void	xerus::misc::copy (T *const __restrict _dest, const T *const __restrict _src, const size_t _n) noexcept
	Copys _n entries from _y to _x, where _y and _x must be disjunkt memory regions. More...
template<typename T , typename std::enable_if< std::is_trivial< T >::value, int >::type = 0>
void	xerus::misc::copy_inplace (T *const _x, const T *const _y, const size_t _n) noexcept
	Copys _n entries from _y to _x, allowing the accessed memry regions of _y and _x to overlap. More...
template<typename T >
void	xerus::misc::copy_scaled (T *const __restrict _x, const T _alpha, const T *const _y, const size_t _n) noexcept
	Copys _n entries from _y to _x, simulationously scaling each entry by the factor _alpha. I.e x = alpha*y. More...
template<class T >
std::unique_ptr< T[]>	xerus::misc::make_unique_array (T *_ptr)
template<typename T >
void	xerus::misc::scale (T *const __restrict _x, const T _alpha, const size_t _n) noexcept
	Scales _n entries of _x by the factor _alpha. I.e. x = alpha*x. More...
template<typename T , typename std::enable_if< std::is_trivial< T >::value, int >::type = 0>
void	xerus::misc::set_zero (T *const __restrict _x, const size_t _n) noexcept
	Sets all entries equal to zero. More...
