Detailed Description

template<class F, class G = typename Realtype<F>::type>
class concepts::AbsoluteComp< F, G >

The component wise absolute value of a element function.

Unless the absolute value is real, the restriction of the methods allow for complex coefficients only complex output. For this case the complex number has only a real part.
