Syntax
chk_fun(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_three operation in the recording; see start recording .

chk_fun
This object must have been created using the chkpoint_two constructor.

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

ax
This argument has prototype
    const ADVector& ax
and its size equal to n = fun.Domain() where fun is the ADFun<Base> function in used the constructor for chk_fun . It specifies vector @(@ x \in \B{R}^n @)@ at which we are computing an AD<Base> version of @(@ y = g(x) @)@.

ay
This argument has prototype
    ADVector& ay
and its size must be equal to m = fun.Range() . The input values of its elements do not matter. Upon return, it is an AD<Base> version of @(@ y = g(x) @)@.
