## $Id$
## $Log$
## Revision 1.3.4.2  2002/09/10 23:24:19  geraint
## Rationalised local and global optimisations.
## Fixes presentation of locally optimised code (ode view).
## Much more elegant :-)
##
## Revision 1.3.4.1  2002/09/03 23:44:43  geraint
## adding global optimisation (-optg).
##
## Revision 1.3  2001/07/27 23:29:10  geraint
## Optimises only when requested (-opt).
##
## Revision 1.2  2001/07/13 04:54:04  geraint
## Branch merge: numerical-algebraic-solution back to main.
##
## Revision 1.1.4.1  2001/05/04 04:07:24  geraint
## Numerical solution of algebraic equations.
## sys_ae.cc written for unsolved inputs.
## Solution of equations using hybrd from MINPACK (as used by Octave fsolve).
##
## Revision 1.1  2000/12/28 12:21:31  peterg
## Put under RCS
##
## Revision 1.2  1997/01/06 21:17:10  peterg
