Detailed Description

Traits for everything that can be an used as a gradient (adjoint, tangent) usually the second template argument of CoDi Gen types codi::RealReverseGen. Possible types are double, codi::RealReverse, codi::Direction etc..

Typedef Documentation

Real

template<typename Gradient >

using codi::GradientTraits::Real = typedef typename TraitsImplementation<Gradient>::Real

The base value used in the gradient entries.

Function Documentation
