Detailed Description

Wrappers for automatic differentiation libraries. Currently there is support for the following libraries:

• Adol-C
• Sacado (a component of Trilinos)

Enumeration Type Documentation

enum Differentiation::AD::NumberTypes

strong

An enumeration to indicate which type of auto-differentiable number is to be used for computations. If a type that is selected for use is not available in the library, a compile-time error will be thrown.

Enumerator
adolc_taped	Taped forward and reverse-mode Adol-C number type (n-differentiable). First derivatives will be computed using reverse mode, while the second derivatives will be computed using forward mode. Even higher-order derivatives can be computed using Adol-C's own driver functions.
adolc_tapeless	Tapeless dynamic forward-mode Adol-C number type (once differentiable).
sacado_dfad	Tapeless dynamic forward-mode Sacado number type (once differentiable).
sacado_dfad_dfad	Tapeless nested dynamic forward-mode Sacado number type (twice differentiable). Both the first and second derivatives will be computed using forward mode.
sacado_rad	Tapeless reverse-mode Sacado number type (once differentiable).
sacado_rad_dfad	Tapeless nested reverse-mode and dynamic forward-mode Sacado number type (twice differentiable). First derivatives will be computed using reverse mode, while the second derivatives will be computed using forward mode.
