Detailed Description

template<typename T>
class at::MatrixRef< T >

MatrixRef - Like an ArrayRef, but with an extra recorded strides so that we can easily view it as a multidimensional array.

Like ArrayRef, this class does not own the underlying data, it is expected to be used in situations where the data resides in some other buffer.

This is intended to be trivially copyable, so it should be passed by value.

For now, 2D only (so the copies are actually cheap, without having to write a SmallVector class) and contiguous only (so we can return non-strided ArrayRef on index).

P.S. dimension 0 indexes rows, dimension 1 indexes columns

Member Function Documentation

template<typename T >

template<typename U >

std::enable_if<std::is_same<U, T>::value, MatrixRef<T> >::type& at::MatrixRef< T >::operator= ( U &&  Temporary )

delete

Disallow accidental assignment from a temporary.

The declaration here is extra complicated so that "arrayRef = {}" continues to select the move assignment operator.

template<typename T >

template<typename U >

std::enable_if<std::is_same<U, T>::value, MatrixRef<T> >::type& at::MatrixRef< T >::operator= ( std::initializer_list< U >  )

delete

Disallow accidental assignment from a temporary.

The declaration here is extra complicated so that "arrayRef = {}" continues to select the move assignment operator.
