1 Introduction

This Mark of the NAG Library is a bug fix and enhancement update.
At Mark 30, 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 1952 user-callable routines while the NAG CL Interface now consists of 1666 routines.

1.1 News at Mark 29.3

The News document for the previous release, Mark 29.3, is available on the NAG website.

2 New Routines at Mark 30

The 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.

3 Internal Changes Affecting the User and Other Known Issues

There have been no internal changes affecting the user at this mark.
For details of all known issues which have been reported for the NAG Library please refer to the Known Issues lists for the Library FL Interface and CL Interface.

4 Withdrawn or Deprecated Routines

At this Mark, the following routines have been withdrawn or are scheduled for withdrawal from the NAG Library, or have been deprecated. For withdrawn routines, warning of their withdrawal has been included in the NAG Library Manual since Mark 28, together with advice on which routines to use instead.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.
