d01pa
is the AD Library version of the primal routine
d01paf.
Based (in the C++ interface) on overload resolution,
d01pa can be used for primal, tangent and adjoint
evaluation. It supports tangents and adjoints of first order.
Note: this function can be used with AD tools other than dco/c++. For details, please contact
NAG.
d01pa
is the AD Library version of the primal routine
d01paf.
d01paf returns a sequence of approximations to the integral of a function over a multidimensional simplex, together with an error estimate for the last approximation.

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.
d01pa preserves all error codes from
d01paf and in addition can return:
