ACS HELP - NAG SUBROUTINE LIBRARIES

NUMERICAL ALGORITHMS GROUP (NAG) FORTRAN AND GRAPHICS LIBRARIES

INTRODUCTION
The NAG FORTRAN Libraries (Mark 14), and Graphics Libraries (Mark 3) have been installed on ACS.** The NAG libraries include routines for:

roots of equations
numerical integration
interpolation
matrix operations
statistical analysis
graphics

**NOTE: As of April 1, 1995, the NAG libraries are only available from ACS & ACS2.

COMMANDS
To compile XL FORTRAN programs which call routines in the NAG libraries, type:

          % xlf [options] filename.f -lnag

where 'filename.f' is your XL FORTRAN source.

To compile XL FORTRAN programs with NAG Graphic Libraries, type:

          % xlf [options] filename.f -lgl -laps -lnfls -lnag

REFERENCES
NAG comes equipped with its own online help system which can be invoked with:

          % naghelp [text]

          -- or --

          % naghelp -tscript filename [text]

where '-tscript' causes naghelp to write a transcript of the help session to 'filename,' and [text] is the optional topic.

Several informative files are available online for learning about NAG. The NAG Essential Information (essint), User Notes (un), and User Notes for NAG Graphics (un) can be read from the following directories:

/usr/local/src/NAG/nagfl14df/doc/essint
/usr/local/src/NAG/nagfl14df/doc/un
/usr/local/src/NAG-GL/naggl03df/doc/un
