## $Log$
## Revision 1.31 2001/07/13 04:54:04 geraint
## Branch merge: numerical-algebraic-solution back to main.
##
## Revision 1.30 2001/07/12 04:02:53 gawthrop
## Now fixes multiports for input and output as well as state
##
## Revision 1.29.2.1 2001/06/26 22:29:05 geraint
## mtt_xargs.sh eliminates Arg list too long error for large models.
## (UNIX xargs does not work if the environment is too large).
##
## Revision 1.29 2001/03/29 19:24:14 gawthrop
## Can now use c representations of crs when using -c option
##
## Revision 1.28 2001/02/05 17:19:52 gawthrop
## Now gives unique names to the states of multiports. Second name
## onwards labeled with port number
##
## Revision 1.27 2000/12/05 12:09:56 peterg
## Changed function name to name()
##
## Revision 1.26 2000/12/05 09:04:54 peterg
## *** empty log message ***
##
## Revision 1.25 2000/12/01 14:51:26 peterg
## Major changes towards partioning
##
## - generates sub ese, def and struc
## - generates indices for conversion of subsystem in/out/state - but not used yet
##
## Revision 1.24 2000/11/30 15:12:55 peterg
## Zapped the declaration of subsystem connections - now in individual
## .def files
##
## Revision 1.23 2000/11/30 15:07:28 peterg
## Sorted out mtt_getsize
##
## Revision 1.22 2000/11/12 17:18:30 peterg
## Changed ' to "
##
## Revision 1.21 2000/10/16 08:40:35 peterg
## Whoops! Must touch mtt_aliased
##
## Revision 1.20 2000/10/16 08:36:31 peterg
## Creat empty _aliased file if it doesn't exist
##
## Revision 1.19 2000/10/12 19:25:39 peterg
## Now generateds the _aliased.txt file
##
## Revision 1.18 2000/09/15 08:09:42 peterg
## Removed another debugging line
##
## Revision 1.17 2000/09/15 08:06:17 peterg
## Removed debug lines
##
## Revision 1.16 2000/09/02 15:55:51 peterg
## *** empty log message ***
##
## Revision 1.15 1998/07/08 14:43:12 peterg
## Restored inforfile
##
## Revision 1.14 1998/07/08 08:26:26 peterg
## Added -I option -- if set prints out the information messages
##
## Revision 1.13 1998/05/12 14:49:10 peterg
## Don't write END; any more - ese-tidy does this now!
##
## Revision 1.12 1998/01/23 13:30:46 peterg
## $RMATRIX --> $MATRIX
##
## Revision 1.11 1997/12/16 18:05:03 peterg
## Increased size of structure vector by on to include unknown_inputs as
## 6th element
##
## Revision 1.10 1997/04/15 09:18:26 peterg
## Added structure file
##
# Revision 1.9 1996/12/07 18:21:25 peterg
# Now uses fopen + file number
#
## Revision 1.8 1996/12/05 10:05:28 peterg
## Removed the Octave switch: empty_list_elements_ok = 1;
## This is now in .octaverc
##
# Revision 1.7 1996/08/30 11:29:49 peter
# Added constitutive relationship to argument list.
# Put in explicit argument list to cbg2ese.
#
# Revision 1.6 1996/08/26 13:25:07 peterg
# Corrected error handling.
#
# Revision 1.5 1996/08/24 14:38:11 peter
# Error handling included.
#
## Revision 1.4 1996/08/19 09:02:12 peter
## Errors go to user - not log.
##
## Revision 1.3 1996/08/18 20:05:55 peter
## Included zero outputs.
##
## Revision 1.2 1996/08/08 18:08:37 peter
## Sorted out file naming scheme.
