atomic_two_afun¶
View page sourceUsing 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
constADVector & 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
\(y = f(x)\).
