An automatic differentiation
<https://en.wikipedia.org/wiki/Automatic_differentiation> C++ library -
Autodiff - is released under the Boost License and is proposed for
inclusion into Boost:
- Github: https://github.com/pulver/autodiff
- Boost Library Incubator:
- Instances of autodiff variables satisfy Boost's Conceptual
Requirements for Real Number Types
In fact the class and function template definitions are based upon the
tables in this page.
- No use of dynamic memory. The only member variable is a std::array<>.
- Consistent with Boost's type promotion templates. When
adding/multiplying/etc. variables of differing dimension number and sizes,
the resulting data type is calculated at compile-time.
- Single header-only file.
- Intuitive and minimal API.
- C++17 compiler that supports constexpr if statements. There are a fair
amount of calculations done at compile-time which would require messy
SFINAE hacks to make this C++14-compatible.
- A github build matrix that also includes clang and MSVC.
- Additional documentation, including the mathematics.
Feedback and endorsements for Boost Library inclusion are welcome and
