File List Name Contents README This document techdoc.html Technical documentation file describing how to use the C Header Files (HTML format). This file contains advice on which header files to choose for your system. examples/*.c C examples referred to in techdoc.html. nagmk20_us.h Header file for the Fortran Library for standard UNIX machines with underscore appended to routine names. nagmk20_nus.h Header file for the Fortran Library for standard UNIX machines with no underscore appended to routine names. nagmk20_cf_us.h Header file for the Fortran Library for UNIX machines with complex functions and underscore appended to routine names. nagmk20_cf_nus.h Header file for the Fortran Library for UNIX machines with complex functions and no underscore appended to routine names. nagmk20_hp64.h Header file for the Fortran Library for HP-UX 64 bit implementations. naggmk4_unix_us.h Header file for the Graphics Library for UNIX machines with underscore appended to routine names. naggmk4_unix_nus.h Header file for the Graphics Library for UNIX machines with no underscore appended to routine names. 2. Applicability The Fortran Library header files contain definitions of all routines in the Mark 15, Mark 16, Mark 17, Mark 18, Mark 19 and Mark 20 NAG Fortran Libraries. The Graphics Library header files contain definitions of all routines in the Mark 4 Graphics Library. Please see the technical documentation in the file techdoc.html to help you choose the correct header files for your system. 3. Distribution Medium The implementation is distributed on CD-ROM, unless otherwise indicated on the medium and accompanying despatch note. 4. Installation Simply copy the appropriate header file(s) and the technical documentation files from the CD-ROM. The HTML file techdoc.html should be installed in a suitable place where users can access it. The directory "examples" and its contents should be copied to the same directory. The appropriate header file(s), one for the Fortran Library and/or one for the Graphics Library, should be installed in a suitable directory where users can access them using the C preprocessor #include <> statement. For example, on Unix systems the file(s) should be copied to the directory /usr/include. You may need to ask a system administrator to do this. The recommended filenames are: Fortran Library: nagmk20.h Graphics Library: naggmk4.h 5. Support from NAG (a) Contact with NAG Queries concerning this document or the implementation generally should be directed initially to your local Advisory Service. If you have difficulty in making contact locally, you can contact NAG directly at one of the addresses given in the Appendix. Users subscribing to the support service are encouraged to contact one of the NAG Response Centres (see below). (b) NAG Response Centres The NAG Response Centres are available for general enquiries from all users and also for technical queries from sites with an annually licensed product or support service. The Response Centres are open during office hours, but contact is possible by fax, email and phone (answering machine) at all times. When contacting a Response Centre it helps us deal with your enquiry quickly if you can quote your NAG site reference and NAG product code (in this case CHGEN20DA). (c) NAG Websites The NAG websites provide information about implementation availability, descriptions of products, downloadable software, product documentation and technical reports. The NAG websites can be accessed at http://www.nag.co.uk/, http://www.nag.com/ (in North America) or http://www.nag-j.co.jp/ (in Japan) (d) NAG Electronic Newsletter If you would like to be kept up to date with news from NAG then please register to receive our free electronic newsletter, which will alert you to special offers, announcements about new products or product/service enhancements, customer stories and NAG's event diary.
