## Revision 1.88 2004/08/29 13:15:28 geraint
## Uses sys_sae instead of sys_ae if sorted equations are being used.
##
## Revision 1.87 2004/08/29 01:46:56 geraint
## Added rules to create ode2odes for sorted system: sesx and sesy.
##
## Revision 1.86 2004/08/29 00:19:49 geraint
## Defaults to noAlgebraicSolver.
##
## Revision 1.85 2003/06/25 12:46:06 gawthrop
## Input only changed one per print interval
## No effect if stepfactor=1
## Fixes bug when _input.m is compiled using -stdin option
## and stepfactor>1
##
## Revision 1.84 2003/04/17 20:57:29 geraint
## Added -sort option to allow direct generation of ode2odes.m using sese.m
## instead of ode/csex.
##
## "mtt -sort rc odeso view" works without Reduce installed!!!
##
## Revision 1.83 2002/08/07 14:27:14 geraint
## Changes to make "-i dassl" work again.
##
## Revision 1.82 2002/07/24 14:00:12 geraint
## Corrected arguments passed to mtt_write when dumping data (sigint).
##
## Revision 1.81 2002/07/11 13:00:23 geraint
## Declared more function arguments to be "const" - improves compiler optimisation.
##
## Revision 1.80 2002/05/22 09:35:49 geraint
## Added insertor variable to stop sh-mode font-lock from getting hopelessly confused by embedded C++.
##
## Revision 1.79 2002/05/20 13:42:31 gawthrop
## Uses simpar.first for first printed output
##
## Revision 1.78 2002/05/11 01:14:17 geraint
## Fix for [ 553218 ] simpar.oct and simpar.m different.
## Translation added between ColumnVector in base .cc and Octave_map in .oct.
##
## Revision 1.77 2002/05/08 16:03:32 geraint
## Added mex support for ode2odes: mtt sys ode2odes mexglx.
## This mex stuff seems to require octave2.1-headers.
##
## Revision 1.76 2002/05/08 14:14:55 geraint
## Tidied up ode2odes code - reduced interweaving of STANDALONE/OCTAVEDLD sections
##
## Revision 1.75 2002/05/07 13:48:42 geraint
## Improved clarity of code generated for -cc and -oct (except ode2odes).

## if necessary.
##
## Revision 1.73 2002/05/01 12:24:41 geraint

##
## Revision 1.72 2002/05/01 12:21:29 geraint
## No longer uses save_ascii_data_for_plotting function to write data
## - eliminates dependence on liboctinterp (and libncurses) for .cc.
##
## Revision 1.71 2002/04/30 23:27:00 geraint
## Replaced octave_map with columnvector in simpar.cc. Not quite as descriptive but
## standardises the interfaces somewhat and reduces the dependency on liboctinterp
## (and thus libreadline, libkpathsea, libncurses, etc).
##
## Revision 1.70 2002/04/28 18:41:27 geraint
## Fixed [ 549658 ] awk should be gawk.
## Replaced calls to awk with call to gawk.
##
## Revision 1.69 2002/04/17 13:46:58 geraint
## #include <fstream> for -oct as well as -cc.
##
## Revision 1.68 2002/04/15 10:54:31 geraint

## Rationalisation of solver code, beginning with algebraic solvers.
##
## Revision 1.63 2001/08/07 04:39:24 geraint
## Consolidated dassl and residual functions.
##
## Revision 1.62 2001/08/01 22:14:32 geraint
## Bug fix for dassl.
##
## Revision 1.61 2001/08/01 04:06:07 geraint
## Added -i dassl for -cc and -oct.
##
## Revision 1.60 2001/07/16 22:23:00 geraint

## Revision 1.57.2.3 2001/06/25 23:28:29 geraint
## Generic mtt_rate and mtt_output - allows method independent calls.
##
## Revision 1.57.2.2 2001/06/05 03:20:40 geraint
## added -ae option to select algebraic equation solution method.
##
## Revision 1.57.2.1 2001/05/04 04:07:24 geraint
## Numerical solution of algebraic equations.
## sys_ae.cc written for unsolved inputs.
