WAdept is a combined automatic differentiation and array software library for the C++ programming language. The automatic differentiation capability facilitates the development of applications involving mathematical optimization. Adept is notable for having applied the template metaprogramming technique of expression templates to speed-up the differentiation of mathematical statements. Along with the efficient way that it stores the differential information, this makes it significantly faster than most other C++ tools that provide similar functionality, although comparable performance has been reported for Stan and in some cases Sacado. Differentiation may be in forward mode, reverse mode, or the full Jacobian matrix may be computed.
