AD Unary Plus Operator
Syntax
`y = + x`
Purpose
Performs the unary plus operation (the result `y` is equal to the operand `x` ).
x
The operand `x` has one of the following prototypes `
const AD<Base> &x
const VecAD<Base>::reference &x
`
y
The result `y` has type `
AD<Base> y
` It is equal to the operand `x` .
Operation Sequence
This is an AD of `Base` atomic operation and hence is part of the current AD of `Base` operation sequence .
Derivative
If f is a Base function , ∂ [ + f ( x ) ] ∂ x = ∂ f ( x ) ∂ x
Example
The file unary_plus.cpp contains an example and test of this operation.
