template<class E1>
auto xt::square(E1 &&e1) noexcept

Square power function, equivalent to e1 * e1.

Returns an xfunction for the element-wise value of of e1 * e1.

Return

an xfunction

Parameters

template<class E1>
auto xt::cube(E1 &&e1) noexcept

Cube power function, equivalent to e1 * e1 * e1.

Returns an xfunction for the element-wise value of of e1 * e1.

Return

an xfunction

Parameters

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

Square root function.

Returns an xfunction for the element-wise square root of e.

Return

an xfunction

Parameters

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

Cubic root function.

Returns an xfunction for the element-wise cubic root of e.

Return

an xfunction

Parameters

template<class E1, class E2>
auto xt::hypot(E1 &&e1, E2 &&e2) noexcept -> detail::xfunction_type_t<math::hypot_fun, E1, E2>

Hypotenuse function.

Returns an xfunction for the element-wise square root of the sum of the square of e1 and e2, avoiding overflow and underflow at intermediate stages of computation.

Return

an xfunction

Note

e1 and e2 can’t be both scalars.
