template<class E>
decltype(auto) real(E &&e) noexcept¶ Return an xt::xexpression representing the real part of the given expression.
The returned expression either hold a const reference to
eor a copy depending on whethereis an lvalue or an rvalue.- Template Parameters
e – The xt::xexpression
-
template<class E>
decltype(auto) imag(E &&e) noexcept¶ Return an xt::xexpression representing the imaginary part of the given expression.
The returned expression either hold a const reference to
eor a copy depending on whethereis an lvalue or an rvalue.- Template Parameters
e – The xt::xexpression
-
template<class E>
inline auto conj(E &&e) noexcept¶ Return an xt::xfunction evaluating to the complex conjugate of the given expression.
- Parameters
e – the xt::xexpression
-
template<class E>
inline auto arg(E &&e) noexcept¶ Calculates the phase angle (in radians) elementwise for the complex numbers in
e.- Parameters
e – the xt::xexpression
-
template<class E>
inline auto angle(E &&e, bool deg = false) noexcept¶ Calculates the phase angle elementwise for the complex numbers in
e.Note that this function might be slightly less perfomant than xt::arg.
- Parameters
e – the xt::xexpression
deg – calculate angle in degrees instead of radians
-
template<class E>
inline auto norm(E &&e) noexcept¶ Calculates the squared magnitude elementwise for the complex numbers in
e.Equivalent to
xt::pow(xt::real(e), 2) + xt::pow(xt::imag(e), 2).- Parameters
e – the xt::xexpression
-
