NAG Library News, Mark 28.4 (April 2022)
1
Introduction
This Mark of the NAG Library is a bug fix and enhancement update.
At Mark 28.4, the NAG Library consists of four main interface sets: the NAG FL Interface, the NAG CL Interface, NAG CPP Interface and the NAG AD Library Interfaces. The NAG FL Interface now consists of 1945 user-callable routines while the NAG CL Interface now consists of 1659. All of these routines are fully documented.
1.1
News at Mark 28.3
The News document for the previous release, Mark 28.3,
is available on the
NAG website.

New Routines at Mark 28.4
The new NAG AD Library routine documents currently available are listed in the
AD Library Contents and there is a direct hyperlink from the NAG FL Interface routine document to its corresponding NAG AD Library routine document, and vice versa.
Since Mark 27.1, all NAG AD Library numerical routines have variants for computing adjoints, tangent linear derivatives or the purely primal computation using consistent interfaces.
Since Mark 27.1, C++ interfaces for a subset of NAG Library are also provided in the NAG CPP Interface. The currently available interfaces are listed in the
CPP Interface Contents.
There are no new routines in the NAG FL Interface in this release. See
the following section for internal changes to existing routines.

Withdrawn or Deprecated Routines
At this Mark, the following routines have been withdrawn or are scheduled for withdrawal from the NAG Library, or have been deprecated. For withdrawn routines, warning of their withdrawal has been included in the NAG Library Manual since Mark 26, together with advice on which routines to use instead.
Please note that unless a Mark of Withdrawal is shown below, the routine will continue to form part of the Library but you are advised to stop using the deprecated routines and to use the recommended replacement routines instead.
Please see the chapter introduction documents and the ‘
FL Interface Replacement Calls Advice’ (or the CL version ‘
CL Interface Replacement Calls Advice’) for more detailed guidance, including advice on how to change a call to the deprecated routine into a call to its recommended replacement, or use the links provided in the following table.
