## Revision 1.9 1997/01/06 21:36:44 peterg
## Fixed bug mtt_error --> mtt_error.txt
## Replaced lsode by Euler integration.
##
## Revision 1.8 1996/09/13 17:54:08 peter
## Now writes default $PARAMS to $1_args.m - $1_ode may use it.
##
## Revision 1.7 1996/09/12 18:41:48 peter
## Standard error handling added.
##
## Revision 1.6 1996/08/24 14:11:04 peter
