Classes
struct	uni20::accessor_applies_conjugation< Accessor >
	Trait used by mdspan accessors that present conjugated values on read. More...
struct	uni20::accessor_applies_conjugation< conjugated_accessor< Accessor > >
class	uni20::conjugated_accessor< Accessor >

Functions
template<MdspanLike Span> requires (uni20::Complex<std::remove_cv_t<typename Span::element_type>> && !accessor_applies_conjugation_v<typename std::remove_cvref_t<Span>::accessor_type>)
constexpr auto	uni20::conj (Span const &span)
	Return a read-only mdspan view that presents conjugated complex values.
template<MdspecLike Span> requires (!MdspanLike<Span> && uni20::Complex<std::remove_cv_t<typename Span::element_type>> && !accessor_applies_conjugation_v<typename std::remove_cvref_t<Span>::accessor_type>)
constexpr auto	uni20::conj (Span const &span)
	Return a read-only deferred view that presents conjugated complex values.
template<MdspanLike Span> requires (uni20::Complex<std::remove_cv_t<typename Span::element_type>> && accessor_applies_conjugation_v<typename std::remove_cvref_t<Span>::accessor_type>)
constexpr auto	uni20::conj (Span const &span)
	Cancel a conjugating mdspan accessor and return the underlying view.
template<MdspecLike Span> requires (!MdspanLike<Span> && uni20::Complex<std::remove_cv_t<typename Span::element_type>> && accessor_applies_conjugation_v<typename std::remove_cvref_t<Span>::accessor_type>)
constexpr auto	uni20::conj (Span const &span)
	Cancel conjugation on a deferred multidimensional view.
template<MdspanLike Span> requires (!uni20::Complex<std::remove_cv_t<typename Span::element_type>>)
constexpr auto	uni20::conj (Span const &span)
	Return a read-only identity view for non-complex mdspan-like views.
template<MdspecLike Span> requires (!MdspanLike<Span> && !uni20::Complex<std::remove_cv_t<typename Span::element_type>>)
constexpr auto	uni20::conj (Span const &span)
	Return a read-only identity view for a non-complex deferred view.

Variables
template<class Accessor >
constexpr bool	uni20::accessor_applies_conjugation_v
	True when an accessor presents conjugated values.
template<AccessorPolicy Accessor, class Domain >
constexpr bool	uni20::enable_accessor_in_domain< conjugated_accessor< Accessor >, Domain >
	Conjugation preserves the execution domains of the wrapped accessor.
template<class Mdspan >
constexpr bool	uni20::mdspan_needs_conjugation_v
	True when an mdspan-like type's accessor presents conjugated values.
