View page sourceAD Unary Minus Operator¶
Syntax¶
y = - x
Purpose¶
Computes the negative of x .
Base¶
The operation in the syntax above must be supported for the case where
the operand is a const Base object.
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 negative of 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_minus.cpp contains an example and test of this operation.
