unary_plus¶
View page sourceAD 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 > & xconst VecAD < Base >:: reference & xy¶
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 ,
Example¶
The file unary_plus.cpp contains an example and test of this operation.
