Detailed Description

template<typename ValueT>
class Sacado::Fad::SimpleFad< ValueT >

Forward-mode AD class using dynamic memory allocation but no expression templates.

This is the user-level class for forward mode AD with dynamic memory allocation, and is appropriate for whenever the number of derivative components is not known at compile time. The user interface is provided by Sacado::Fad::GeneralFad.
