Detailed Description

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

Member pointer backed tensor.

Template Parameters

D	Derived type.

This allows users to interpret arbitrary buffers as tensor objects. The user specified buffer is assumed to be at least as large as the tensor's maximum size and elements are read and written to the buffer in row major order.

Traits information for this type.

See also: internal::traits

Constructor & Destructor Documentation

template<class D>

constexpr lin::internal::TensorView< D >::TensorView ( typename Traits::elem_t * elems )

inline

Constructs a new tensor tensor view with the provided backing array.

Parameters

elems Element backing array.

The element backing array is a assumed to be in row major order. Elements of the tensor initially hold whatever values were left in the backing array.

The backing array should be at least as large as the maximum size of the tensor (see internal::traits information).

The size of the tensor defaults to the maximum allowed size.

template<class D>

constexpr lin::internal::TensorView< D >::TensorView	(	typename Traits::elem_t *	elems,
		size_t	r,
		size_t	c
	)

inline

Constructs a new tensor tensor view with the provided backing array and requested dimensions.

Parameters

elems	Element backing array.
r	Initial row dimension.
c	Initial column dimension.

The element backing array is a assumed to be in row major order. Elements of the tensor initially hold whatever values were left in the backing array.

The backing array should be at least as large as the maximum size of the tensor (see internal::traits information).

Lin assertions errors will be triggered if the requested dimensions aren't possible given the tensor's traits.

Member Function Documentation

template<class D>

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

inline

Retrives a pointer to the element backing array.

Returns: Pointer to the backing array.

This is the same buffer the tensor view was constructed with.
