Functions
template<MemoryArray A>
auto	nda::flatten (A &&a)
	Flatten an nda::basic_array or nda::basic_array_view to a 1-dimensional array/view by reshaping it.
template<MemoryArray A, typename... IdxGrps>
auto	nda::group_indices_view (A &&a, IdxGrps...)
	Create a new nda::basic_array or nda::basic_array_view by grouping indices together of a given array/view.
template<MemoryArray A, typename NewLayoutType>
auto	nda::map_layout_transform (A &&a, NewLayoutType const &new_layout)
	Transform the memory layout of an nda::basic_array or nda::basic_array_view.
template<uint64_t Permutation, MemoryArray A>
auto	nda::permuted_indices_view (A &&a)
	Permute the indices/dimensions of an nda::basic_array or nda::basic_array_view.
template<int N, typename A> requires (nda::is_regular_or_view_v<A>)
auto	nda::reinterpret_add_fast_dims_of_size_one (A &&a)
	Add N fast varying dimensions of size 1 to a given nda::basic_array or nda::basic_array_view.
template<MemoryArray A, std::integral... Ints>
auto	nda::reshape (A &&a, Ints... is)
	Reshape an nda::basic_array or nda::basic_array_view.
template<MemoryArray A, std::integral Int, auto R>
auto	nda::reshape (A &&a, std::array< Int, R > const &new_shape)
	Reshape an nda::basic_array or nda::basic_array_view.
template<MemoryArray A, std::integral Int, auto newRank>
auto	nda::reshaped_view (A &&a, std::array< Int, newRank > const &new_shape)
template<typename A> requires (MemoryArray<A> or is_instantiation_of_v<expr_call, A>)
auto	nda::transpose (A &&a)
	Transpose the memory layout of an nda::MemoryArray or an nda::expr_call.
template<int I, int J, MemoryArray A> requires (is_regular_or_view_v<A>)
auto	nda::transposed_view (A &&a)
	Transpose two indices/dimensions of an nda::basic_array or nda::basic_array_view.
