Detailed Description

template<typename ValueT, int Num>
class Sacado::ELRCacheFad::SFad< ValueT, Num >

Forward-mode AD class using static memory allocation, caching expression templates, and expression-level reverse mode.

This is the user-level class for forward mode AD with static memory allocation, and is appropriate for whenever the number of derivative components is known at compile time. The size of the derivative array is fixed by the template parameter Num. It is similar to Sacado::ELRFad::SFad, except it uses the caching expression templates that cache the results of val() calculations for later dx() calculations.
