Projects / AutoDiff.NET


AutoDiff.NET is a pure .NET library that allows a developer to easily compose functions symbolically and then automatically calculates the function's value and gradient at any given point. It can be very useful in conjunction with a gradients-based optimization library. It has been tested to work on Mono 2.10 on Linux and on .NET4 on Windows.

    •  31 Oct 2011 17:06

      Release Notes: The IntPower class has been renamed from ConstPower, breaking the API. A TermPower class was added. A division operator was added. User defined nary functions are now provided in addition to unary and binary functions. Evaluation of gradients using a subset of the variables was implemented. This is used for parameterized functions having "constant" parameters in addition to the actual function argument. Power terms can now have terms in the exponent, in addition to constants.
