Functions

template<class E> inline auto erf(E &&e) noexcept -> detail::xfunction_type_t<math::erf_fun, E>

Error function.

Returns an xfunction for the element-wise error function of e.

template<class E> inline auto erfc(E &&e) noexcept -> detail::xfunction_type_t<math::erfc_fun, E>

Complementary error function.

Returns an xfunction for the element-wise complementary error function of e, whithout loss of precision for large argument.

template<class E> inline auto tgamma(E &&e) noexcept -> detail::xfunction_type_t<math::tgamma_fun, E>

Gamma function.

Returns an xfunction for the element-wise gamma function of e.

template<class E> inline auto lgamma(E &&e) noexcept -> detail::xfunction_type_t<math::lgamma_fun, E>

Natural logarithm of the gamma function.

Returns an xfunction for the element-wise logarithm of the asbolute value fo the gamma function of e.
