Whenever the NAG Fortran Library has been supplied in compiled form, that form is considered to be the standard library file. The use of all supplied software must be in accordance with the terms and conditions of the Software Licence signed by NAG and each site. In particular, users must not have free access to the text of the library routines. Any request to use NAG software on a computer other than the one licensed must be referred to NAG (see Section 6).
This implementation is a compiled, tested, ready-to-use version of the NAG Fortran Library that is considered suitable for operation on the computer systems detailed below:
hardware: DEC computers with MIPS R2000 or R3000 RISC CPUs,
e.g. DECstations 2100, 3100, 5000,
DECsystems 5000, 5100, 5500, 58x0
operating system: Ultrix 4.4 or compatible
Fortran compiler: DEC Fortran 77 Version 3.2 or compatible
For information about implementations of the NAG Fortran Library for use on other computer systems please contact NAG.
This implementation was produced at the Computing Centre of Cardiff University on the computing system detailed below:
hardware: DECstation 5000/125 operating system: Ultrix 4.4 (Rev. 69) Fortran compiler: DEC Fortran 77 Version 3.2-164 compiler options: -O4
The entire NAG Fortran Library, Mark 19, was compiled with full optimization (-O4), except for the following routines, which had to be compiled at lesser optimization levels:
d01ajvt.f (-O2) d01atvt.f (-O2) d03eaft.f (-O1) e02ahzt.f (-O2) x04dbft.f (-O0)
This library has been tested using the Basic Linear Algebra Subprograms (BLAS) and linear algebra routines (LAPACK) provided by NAG (see the Chapter Introductions for F06, F07 and F08 in the NAG Fortran Library Manual) only.
For further details, refer to other documentation supplied or contact NAG (see Section 6).

compiled library: 17.1 Mb example program material: 5.9 Mb documentation files: 2.5 Mb scripts: 0.3 Mb library source code: 19.1 Mb (not needed on disk permanently)
To install all material (including source), use the Unix tar utility, e.g.
tar xvf /cdrom/fl19.tar(assuming the CD-ROM has been mounted as /cdrom).
Source should be needed only for reference by whoever is responsible for the installation of the library. This material should not be made available to users.
The object library (libnag.a) should be moved to a directory, such as /usr/lib, in the default search path of the linker, if possible, so that linkage is convenient. After the object library is in place, run ranlib, e.g.
ranlib /usr/lib/libnag.a
The script nagexample refers to the local directory containing the example programs. The file should be copied to (for example) /usr/local/bin, modified to reflect the local installation, and its protection set to world execute.
The man page, which directs users to the HTML form of the Users' Note, should be moved to a directory in the man search path, e.g.
cd doc mv nag_fl_un.3 /usr/local/man/man3
The following material should also be made accessible to users:

Note that the example material has been adapted, if necessary, from that printed in the NAG Fortran Library Manual, so that programs are suitable for execution with this implementation with no further changes (but see Section 4.4.2 for comments about possible differences in results obtained). Making the example material directly available to users provides them with easily adaptable templates for their own problems.
The "example programs" for the routines in the F06 chapter are not typical example programs and they are not in the Library Manual. They are test programs, which are supplied to sites for use in an installation test of the Library. Some of them take much longer to run than other example programs. Routines which are equivalent to BLAS, are tested twice: once when called by their NAG F06 names, and once when called by their BLAS names.
On-line documentation is bundled with this implementation. Please see the Readme file on the distribution medium for further information.
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 please quote your NAG site reference and NAG product code (in this case FLD3119DA).
The NAG websites are an information service providing items of interest to users and prospective users of NAG products and services. The information is reviewed and updated regularly and includes implementation availability, descriptions of products, downloadable software, product documentation and technical reports.
