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

Functions
template<MemoryMatrix A>
int	nda::blas::get_ld (A const &a)
	Get the leading dimension in LAPACK jargon of an nda::MemoryMatrix.
template<MemoryMatrix A>
int	nda::blas::get_ncols (A const &a)
	Get the number of columns in LAPACK jargon of an nda::MemoryMatrix.

Variables
template<bool conj, bool transpose>
const 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< conj_f, A > > = true
	Specialization of nda::blas::is_conj_array_expr for the conjugate lazy expressions.
