NAG Fortran Library
Mark 17

On-line Documentation

Introduction

The NAG Fortran Library is a comprehensive collection of Fortran 77 routines for the solution of numerical and statistical problems. The word routine is used to denote subroutine or function.

We support Mark 17 of the library on Solaris 2, IRIX 6 and Windows 95/NT machines. SunOS 4, IRIX 5 and DOS systems should continue to use Mark 16 for the moment.

Refer to the "User's Notes" for instructions on how to compile and link your program with the library.

NAG Documentation

This index allows you to view the various text files supplied by NAG with the software.

• The Essential Introduction to the Library.

• The Users' Notes - implementation specific information for each supported platform.
  • Suns running Solaris 2.X
  • Silicon Graphics running Irix 6.X
  • PCs running Windows 95/NT

• What has changed in this release?
  • New and enhanced routines.
  • Routines withdrawn as of Mark 17, with suggested replacements.

• A summary of the routines, giving a one or two line description of each.

• Relationships between the routines. Two lists are available which indicate which routines call other routines.
  • Sorted by calling routine (ie. "which other routines does routine X make calls to?").
  • Sorted by called routine (ie. "which routines call routine X?").

• Equivalence of the NAG routines and Basic Linear Algebra Subprograms (BLAS).
  • BLAS and LAPACK equivalents of NAG routines.
  • NAG equivalents of BLAS and LAPACK routines.

Notes For C Programmers

C programmers can link against the Fortran version of the library if they can produce a suitable function prototype declaration to go with each routine they wish to use (by inspection of the data types passed and returned when calling the routine from Fortran). NAG publish some notes on this process on their Web server. We have made available the nagf.h include file (in /usr/local/include).

Note: If you are linking against NAG library you need to also link against the Fortran library and the standard maths library.
