Detailed Description

template<typename DataType_, typename Extents_, typename LayoutPolicy_>
class Arcane::MDSpan< DataType_, Extents_, LayoutPolicy_ >

Base class for multidimensional views.

This class is inspired by the std::mdspan class currently being defined (see http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2021/p0009r12.html)

This class is used to manage views on arrays such as NumArray. The methods of this class are accessible on the accelerator.

For more information, refer to the page Usage of the NumArray class.
