GENMEX - utility to generate mex-files for MATLAB 4.x (and 5) that call
fortran (especially NAG) library routines.

GENMEX generates a MATLAB mex-file (written in c) that calls given
fortran subroutine GENMEX knows about.

GENMEX is written and tested in SUN Solaris 2.3 environment and
depends on way how fortran routines are called from c-language in
Solaris. 

This is highly experimental and no succeed on using this is
guaranteed. Otherwise you are free to use this program. If you modify
the source code please let me know. Anyway I'd be glad to know if you
find this useful.

Install as described in file INSTALL and check the demo .m files with
names *_demo.m .

There is a set of documentations for GENMEX made by Grant Keady,
University of Western Australia (keady@maths.uwa.edu.au), available at
http://maths.uwa.edu.au/~keady/genmex/gendoc.html

nag_routines.dat-file was converted from InterCall-data files and
surely contains errors due the conversion. InterCall is a
'Mathematica-numerical library'-interface by Dr. Terry Robb. 
InterCall is sold by Analytica, http://www.analytica.com.au.

If MATLAB runs into a bus error or segmentation fault when using
GENMEX-generated MATLAB-functions it is due to:
1. Error in GENMEX generated c-code.
2. Error in defaults file (length of workspace variables is too
   small etc.)

If fortran routine writes to standard output (channel 6) it also kills
the MATLAB session.

GENMEX is available from

The 'nms'-library from the book:  "Numerical Methods and Software"
by D. Kahaner, C. Moler, S. Nash, Prentice Hall 1988, which, along with
NAG, can be used with GENMEX, is available as 
http://www.helsinki.fi/~mjlaine/genmex/nms.tar.gz.
