doublereal is the C++ type that corresponds
to Fortran single and double precision.
This type is mapped to an AD type that depends on the library being used:
| Library | typedef |
libf2c_adolc.a |
typedef adouble doublereal
|
libf2c_cppad.a |
typedef CppAD::<double> doublereal
|
libf2c_fadbad.a |
typedef F<double> doublereal
|
integer is the C++ type that corresponds
to Fortran integers.
doublereal type has a tape state and
the initial tape state is Empty.
n
has prototype
integer n
x
has prototype
doublereal *x
n
that contains the independent variables
(and values) for this function recording.
The value of the elements of
x
are not affected by calling this routine.
(The elements are not const in the prototype
because the AD information connected to them may be affected.)
m
has prototype
integer m
y
has prototype
doublereal *x
m
that contains the dependent variables (and values)
for this function recording.
The value of the elements of
y
are not affected by calling this routine.
(The elements are not const in the prototype
because the AD information connected to them may be affected.)
i
has prototype
integer i
j
has prototype
integer j
Partial
is the partial derivative of the i-th dependent variable
with respect to the j-th dependent variable
(i-th function value with respect to j-th function argument).
z
has prototype
const doublereal &z
doublereal object
z
.
x
and
y
have prototypes
doublereal* x
doublereal* y
\[
\left\{ \begin{array}{ll}
+ |x| & \R{if} \; y \geq 0
\\
- |x| & \R{otherwise}
\end{array} \right.
