Detailed Description

template<class EC, std::size_t N, layout_type L, class Tag>
class xt::xtensor_adaptor< EC, N, L, Tag >

Dense multidimensional container adaptor with tensor semantics and fixed dimension.

The xtensor_adaptor class implements a dense multidimensional container adaptor with tensor semantics and fixed dimension. It is used to provide a multidimensional container semantic and a tensor semantic to stl-like containers.

Template Parameters

EC	The closure for the container type to adapt.
N	The dimension of the adaptor.
L	The layout_type of the adaptor.
Tag	The expression tag.
