Detailed Description

template<typename T, typename Storage>
class Sacado::ELRFad::GeneralFad< T, Storage >

Forward-mode AD class templated on the storage for the derivative array.

This class provides a general forward mode AD implementation for any type of derivative array storage. It does not incorporate expression templates.
