Classes
struct	nda::tensor::tensor_view< T >
	A type-erased, non-owning view of an nda::MemoryArray or a conjugate lazy expression. More...

Typedefs
template<typename T>
using	nda::tensor::const_tensor_view = tensor_view<const T>
	Alias for a tensor_view with const value type.
template<BlasArrayOrConj A>
using	nda::tensor::data_ptr_t = decltype(get_array(std::declval<A>()).data())
	Data pointer type of an nda::blas_lapack::BlasArrayOrConj.

Enumerations
enum class	nda::tensor::binary_op : std::uint8_t
	Binary operations for tensor operations. More...
enum class	nda::tensor::unary_op : std::uint8_t
	Unary element-wise operations for tensor operations. More...

Functions
template<int R> requires (R >= 0 && R <= 26)
std::string_view	nda::tensor::default_index ()
	Generate a default index string ("abc...") of a given length.
void	nda::tensor::require_equal_indices (std::string_view idx_a, std::string_view idx_b, int rank, std::string_view op_name)
	Check if two index strings are equal and have a specified length.

Variables
static constexpr bool	nda::tensor::have_cutensor = false
	Constexpr variable that is true if nda is configured cuTENSOR support.
static constexpr bool	nda::tensor::have_tblis = false
	Constexpr variable that is true if nda is configured with TBLIS support.
