Detailed Description

template<class D>
class lin::internal::Tensor< D >

Member array backed tensor.

Template Parameters

D	Derived type.

This is the most commonly used implementation of the internal::Base interface. Tensor elements are stored contiguously in a member backing array in row major order.

This type is directly derived by the user facing Matrix, RowVector, and Vector types.

Constructor & Destructor Documentation

template<class D>

constexpr lin::internal::Tensor< D >::Tensor ( )

inline

Constructs a new tensor with zeros initialized elements and the largest allowable dimensions.

See also: internal::traits

template<class D>

constexpr lin::internal::Tensor< D >::Tensor	(	size_t	r,
		size_t	c
	)

inline

Constructs a tensor with zeros initialized elements and the requested dimensions.

Parameters

r	Initial row dimension.
c	Initial column dimesnion.

See also: internal::traits

template<class D>

template<typename T >

constexpr lin::internal::Tensor< D >::Tensor ( std::initializer_list< T > const & list )

inline

Constructs a tensor with elements initialized from an initializer list.

Template Parameters

T	Element type of the initializer list.

Parameters

list	Initializer list.

The tensor dimensions defaults to the largest allowable dimensions and the initializer list must be assignable to a tensor of this type.

See also: internal::traits; internal::Mapping::operator=(std::initializer_list<T> const &); internal::Tensor::Tensor(size_t, size_t, std::initializer_list<T> const &)

template<class D>

template<typename T >

constexpr lin::internal::Tensor< D >::Tensor	(	size_t	r,
		size_t	c,
		std::initializer_list< T > const &	list
	)

inline

Constructs a tensor with elements initialized from an initializer list and the requested dimensions.

Template Parameters

T	Element type of the initializer list.

Parameters

r	Initial row dimension.
c	Initial column dimensions.
list	Initializer list.

The initializer list must be assignable to a tensor of this type.

See also: internal::traits; internal::Mapping::operator=(std::initializer_list<T> const &); internal::Tensor::Tensor(std::initializer_list<T> const &)

template<class D>

template<class C >

constexpr lin::internal::Tensor< D >::Tensor ( Stream< C > const & s )

inline

Constructs a tensor by copying in dimensions and elements from another tensor stream.

Template Parameters

C	Other derived type.

Parameters

s	Other tensor stream.

The tensor will automatically attempt to resize to the dimensions of the other tensor stream.

The stream must be assignable to a tensor of this type.

See also: internal::Mapping::operator=(Stream<C> const &)

Member Function Documentation

template<class D>

constexpr Traits::elem_t* lin::internal::Tensor< D >::data ( )

inline

Retrives a pointer to the element backing array.

Returns: Pointer to the backing array.

The elements of the tensor are layed out in row major order in the backing array. They are stored continguously in memory.
