This is version 31.1.0.0 of a set of C++ interfaces for the NAG Library,supplied as a series of header files.

In order to make use of this product you will need a copy ofMark 31.1 of the NAG Libraryinstalled on your system.

Currently only interfaces for a small subset of routines from the NAG Libraryare available in this form. These interfaces are automatically generated, andtheir primary purpose is to elicit feedback on their design prior to rollingthe process out across the whole library.

Please visit theNAG Library for C++ landing pagefor quick-start information and more details on the examples supplied in thedistribution.

Assuming that you have installed the C++ interfaces into the directory called[NAGCPP_INSTALL_DIR] then you should have four subdirectories:

• [NAGCPP_INSTALL_DIR]/include

  Contains the C++ wrappers and all required utility headers.

• [NAGCPP_INSTALL_DIR]/examples

  Contains a sample of examples calling the interfaces.

• [NAGCPP_INSTALL_DIR]/tests

  Contains a series of unit tests that have been used to test the suppliedwrappers.

• [NAGCPP_INSTALL_DIR]/scripts

  Contains a number of Linux scripts for compiling and running the examplesand unit tests. These scripts can also be run from WSL or Cygwin. Beforerunning any of these scripts you should ensure that your environment is setup correctly by, for example, running eitherenvvars.bat,nagvars.sh ornagvars.csh, supplied with the NAG Library. Which is supplied / requireddepends on whether you are on Windows or Linux and, if on Linux, which shellyou are using.

When using the C++ interfaces supplied with this readme you will need to addthe directory[NAGCPP_INSTALL_DIR]/include to the list of directories yourcompiler searches for header files in addition to using any compiler flagsusually required by the NAG Library (as specified in the Users' Notes suppliedwith your version of the library and also available from the NAG website athttps://support.nag.com/content/nagr-library-mark-31).
