Detailed Description

template<typename ValueT>
class Sacado::CacheFad::DFad< ValueT >

Forward-mode AD class using dynamic memory allocation and caching expression templates.

This is a 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::CacheFad::GeneralFad. It is similar to Sacado::Fad::DFad, except it uses the caching expression templates that cache the results of val() calculations for later dx() calculations.
