Here is a link to its current documentation . Using AD Version of Atomic Function
Syntax
afun(ax, ay)

Purpose
Given ax , this call computes the corresponding value of ay . If AD<Base> operations are being recorded, it enters the computation as an atomic operation in the recording; see start recording .

ADVector
The type ADVector must be a simple vector class with elements of type AD<Base> ; see Base .

afun
is a atomic_user object and this afun function call is implemented by the atomic class.

ax
This argument has prototype



    const ADVector& ax

and size must be equal to n . It specifies vector @(@ x \in \B{R}^n @)@ at which an AD<Base> version of @(@ y = f(x) @)@ is to be evaluated; see Base .

ay
This argument has prototype



    ADVector& ay

and size must be equal to m . The input values of its elements are not specified (must not matter). Upon return, it is an AD<Base> version of @(@ y = f(x) @)@.
