d02pt
is the AD Library version of the primal routine
d02ptf.
Based (in the C++ interface) on overload resolution,
d02pt can be used for primal, tangent and adjoint
evaluation. It supports tangents and adjoints of first and second order.
Corresponding to the overloaded C++ function, the Fortran interface provides five routines with names reflecting the type used for active real arguments. The actual subroutine and type names are formed by replacing AD and ADTYPE in the above as follows:
The function is overloaded on ADTYPE which represents the type of active arguments. ADTYPE may be any of the following types: double, dco::ga1s<double>::type, dco::gt1s<double>::type, dco::gt1s<dco::gt1s<double>::type>::type, dco::ga1s<dco::gt1s<double>::type>::type
Note: this function can be used with AD tools other than dco/c++. For details, please contact NAG.
3Description
d02pt
is the AD Library version of the primal routine
d02ptf.
d02ptf provides details about an integration performed by either d02pef, d02pff or d02pgf.
For further information see Section 3 in the documentation for d02ptf.

5Arguments
In addition to the arguments present in the interface of the primal routine,
d02pt includes some arguments specific to AD.
A brief summary of the AD specific arguments is given below. For the remainder, links are provided to the corresponding argument from the primal routine.
A tooltip popup for all arguments can be found by hovering over the argument name in Section 2 and in this section.
On entry: a configuration object that holds information on the differentiation strategy. Details on setting the AD strategy are described in AD handle object in the NAG AD Library Introduction.
