Simple Automatic Differentiation

v1.2 · Dec 18, 2024 · MIT + file LICENSE

Description

Handles both vector and matrices, using a flexible S4 class for automatic differentiation. The method used is forward automatic differentiation. Many functions and methods have been defined, so that in most cases, functions written without automatic differentiation in mind can be used without change.
