Exponential functions

xtensor provides the following exponential functions for xexpressions:

Defined in xtensor/xmath.hpp

template<class E>
auto xt::exp(E &&e) noexcept -> detail::xfunction_type_t<math::exp_fun, E>

Natural exponential function.

Returns an xfunction for the element-wise natural exponential of e.

Return

an xfunction

Parameters

template<class E>
auto xt::exp2(E &&e) noexcept -> detail::xfunction_type_t<math::exp2_fun, E>

Base 2 exponential function.

Returns an xfunction for the element-wise base 2 exponential of e.

Return

an xfunction

Parameters

template<class E>
auto xt::expm1(E &&e) noexcept -> detail::xfunction_type_t<math::expm1_fun, E>

Natural exponential minus one function.

Returns an xfunction for the element-wise natural exponential of e, minus 1.

Return

an xfunction

Parameters

template<class E>
auto xt::log(E &&e) noexcept -> detail::xfunction_type_t<math::log_fun, E>

Natural logarithm function.

Returns an xfunction for the element-wise natural logarithm of e.
