# XAD High-Performance Automatic Differentiation for Python and C++

XAD is a comprehensive open-source library for automatic differentiation for Python and C++, targeting production code at any scale.

Latest Release: v1.5.2

## Automatic Differentiation

Automatic differentiation (also called algorithmic differentiation) is a set of techniques for calculating partial derivatives of functions specified as computer programs. Since every program execution is always composed of a sequence of simple operations with known derivatives (arithmetics and mathematical functions like sin, exp, log, etc.), the chain rule can be applied repeatedly to calculate partial derivatives automatically. See automatic differentation mathematical background for more details.
