Typedefs
using	nda::dcomplex = std::complex<double>
	Alias for std::complex<double> type.

Functions
template<Array A> requires (MemoryArray<A> or is_conj_array_expr<A>)
MemoryArray decltype(auto)	nda::blas::get_array (A &&a)
	Get the underlying array of a conjugate lazy expression or return the array itself in case it is an nda::MemoryArray.
template<MemoryArray A> requires (get_rank<A> == 1 or get_rank<A> == 2)
int	nda::blas::get_ld (A const &a)
	Get the leading dimension of an nda::MemoryArray with rank 1 or 2 for LAPACK calls.
template<MemoryArray A> requires (get_rank<A> == 1 or get_rank<A> == 2)
int	nda::blas::get_ncols (A const &a)
	Get the number of columns of an nda::MemoryArray with rank 1 or 2 for BLAS/LAPACK calls.

Variables
template<Array A>
static constexpr char	nda::blas::get_op
	Variable template that determines the BLAS matrix operation tag ('N','T','C') based on the given boolean flags for conjugation and transposition.
template<Array A>
static constexpr bool	nda::blas::has_C_layout
	Constexpr variable that is true if the given nda::Array type has a C memory layout.
template<Array A>
static constexpr bool	nda::blas::has_F_layout
	Constexpr variable that is true if the given nda::Array type has a Fortran memory layout.
template<typename A>
static constexpr bool	nda::blas::is_conj_array_expr = false
	Constexpr variable that is true if the given type is a conjugate lazy expression.
template<MemoryArray A>
static constexpr bool	nda::blas::is_conj_array_expr< expr_call< detail::conj_f, A > > = true
	Specialization of nda::blas::is_conj_array_expr for the conjugate lazy expressions.
