CppADCodeGen performs hybrid Automatic Differentiation (AD), that is, uses operator-overloading and produces source-code. Such source-code can be statically compiled at runtime using an existing compiler and linked dynamically or, alternatively, go through a JIT compilation using Clang/LLVM.
In addition to C source generation, CppADCodeGen can also produce Latex, html+MathML, and dot source-code files for your algorithm. Latex sources can be used to create PDF files for documentation purposes, html+MathML can be used to display your algorithm in a web browser, and dot files can be used to create images with a graph of your model (see graphviz).
CppADCodeGen can also be used to perform differentiation index reduction of Differential Algebraic Equations (DAE) through Pantelides, Soares-Secchi, and Dummy Derivatives methods.
CppADCodeGen is built on top of the CppAD library, which is a header only C++ AD library using operator overloading.
CppADCodeGen is available with both the EPL and GPL licenses (suitable for both open-source and closed-source commercial projects). See epl-v10.txt and gpl3.txt for a copy of the licenses.
CppADCodeGen is a C++11 header only library so there aren't many dependencies:
- CppAD (2016),
- A C++11 compiler (such as GCC and Clang),
- Clang/LLVM 3.2, 3.4, 3.6, or 3.8 (only for JIT compilation), and
- Eigen 3 (only for DAE differentiation index reduction).
Runtime compilation and dynamic linking:
- Linux (it might be very easy to support other OSes but it is not implemented yet)
Just copy the contents of the folder include to anywhere you would like to include from.
A debian installation package can be created at the root of the project. Typically you can create the installer by just typing:
It will create a debian package outside the project's folder.
See the wiki.
