Note: a1w denotes that first order adjoints are computed in working precision; this has the corresponding argument type
nagad_a1w_w_rtype.
Also available is the
t1w (first order tangent linear) mode, the interface of which is implied by replacing
a1w by
t1w throughout this document.
Additionally, the
p0w (passive interface, as alternative to the FL interface) mode is available and can be inferred by replacing of active types by the corresponding passive types.
The method of codifying AD implementations in the routine name and corresponding argument types is described in the
NAG AD Library Introduction.
