ADExpressions is a software which communicates (via MathLink protocol) 
and provides compatibility between the representation of
nonlinear functions, specified as Mathematica expressions, and
objects of suitable classes supported by the C-XSC automatic differentiation modules.
Details about the design, implementation and the application of ADExpressions software
can be found in

The software ADExpressions is designed as an auxiliary tool.
Although based on MathLink protocol for communicating the
expressions, this basic software does not contain functions
installable in Mathematica. Its purpose is to facilitate the
development of such functions, that is, the implementation of
external MathLink programs that integrate C-XSC routines for,
or routines based on C-XSC automatic differentiation arithmetic. 

ADExpressions is split into three files: 
types.h, 
expression.h 
expression.cpp 

Everyone who wants to use the software shall
include expression.h in the source file of the own MathLink program.

Examples of installable MathLink programs which use ADExpressions
are contained in:
