## Revision 1.54 2002/07/11 13:00:23 geraint
## Declared more function arguments to be "const" - improves compiler optimisation.
##
## Revision 1.53 2002/06/10 23:22:16 geraint
## Fixed problem with Matlab fsolve failing because of "user function returned Inf or Nan" (fsolve.m, line 245).
##
## Revision 1.52 2002/05/27 14:52:15 geraint
## Parameters in sfun reps are now declared using sympar.h at the top of the
## sfun*.c file instead of in individual functions. This causes the optimisation
## variables (mtt_tmp*) to be declared correctly without causing conflicts in the
## scope of parameter declarations.
##
## Revision 1.51 2002/05/19 13:01:21 geraint
## Numerical solution of algebraic equations implemented for S-function target.
##
## Equation solving requires the Matlab Optimization Toolbox to be installed.
##
## Code has been changed from C++ to C to allow mex files to be built with LCC,
## the compiler bundled with Matlab.
##
## Parameters are now obtained from numpar.c instead of a dialogue box.
##
## `mtt <sys> sfun zip` creates all necessary files for building the model mex files.
##
## Revision 1.50 2002/05/15 14:22:25 geraint
## Code for Simulink S-function target written direct to sfun.cc instead of
## calling .mexglx files. This eliminates the sfun dependency on Octave
## ColumnVectors. sys_sfun.cc should build directly on a MS Windows machine
## (can't test this yet).
##
## added sfun.zip target to create source code to export.
##
## Revision 1.49 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 1.48 2002/05/08 14:51:03 geraint
## Moved matlab/octave data type conversion functions to a separate file.
##
## Revision 1.47 2002/05/07 23:50:34 geraint
## Preliminary support for Matlab dynamically linked shared objects:
## invoke with: mtt -cc sys rep mexglx
## ode2odes support is not yet included.
##
## Revision 1.46 2002/05/07 13:48:43 geraint
## Improved clarity of code generated for -cc and -oct (except ode2odes).
## Octave DEFUN_DLDs now call (rather than replace) their .cc equivalents.
##
## Revision 1.45 2002/05/02 09:30:22 gawthrop
## _ssim.m now returns t as 4th arg
##
## Revision 1.44 2002/05/01 17:30:56 geraint
## Improved pre-processor directives to better accommodate future alternatives (matlab)
## if necessary.
##
## Revision 1.43 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 1.42 2002/04/28 18:41:27 geraint
## Fixed [ 549658 ] awk should be gawk.
## Replaced calls to awk with call to gawk.
##
## Revision 1.41 2002/04/23 17:46:05 gawthrop
## _sim.m now returns time as third argument
##
## Revision 1.40 2002/04/17 16:23:59 geraint
## Partial fix for [ 545113 ] zeros missing in c++.
## Fixes -oct by removing duplicate initialisation (-c is still outstanding).
##
## Revision 1.39 2002/04/15 10:54:31 geraint
## Statically declare outputs and initialise to zero.
## This is necessary to prevent spurious values from being output when no assignments are made (i.e. when "y(i) := 0 for all u" (Reduce:see NERO)).
##
## Revision 1.38 2001/07/23 23:43:15 gawthrop
## header only version does not need to compute sizes from _def.r
##
## Revision 1.37 2001/07/13 04:54:04 geraint
## Branch merge: numerical-algebraic-solution back to main.
##
## Revision 1.36 2001/07/12 04:00:51 gawthrop
## Now zeros y correctly - ie Ny NOT Nx elements
##
## Revision 1.35 2001/06/13 10:39:51 gawthrop
## Zeros output matices in csex and cseo just in case some elements are
## actually zero and not set in code. Works for m and oct.
##
## Revision 1.34 2001/05/26 18:36:43 gawthrop
## Further modifications. Now works on rcPPP
## -- next jobs:
## add identification to ppp_nlin_sim
## create real-time ppp_nlin_run
##
## Revision 1.33 2001/05/26 15:46:38 gawthrop
## Updated to account for new nonlinear ppp
##
## Revision 1.32 2001/05/24 07:42:12 gawthrop
## Included and updated the missing tf_r2m
##
## Revision 1.31.2.2 2001/07/02 00:34:56 geraint
## gcc-3.0 compatibility.
##
## Revision 1.31.2.1 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 1.31 2001/04/03 14:49:42 gawthrop
## Revised to incorporate new ssim (sensitivity simulation)
## representation (m only just now).
##
## Revision 1.30 2001/03/30 15:13:58 gawthrop
## Rationalised simulation modes to each return mtt_data
##
## Revision 1.29 2001/03/27 13:10:23 geraint
## Improved determination of Octave version.
##
## Revision 1.28 2001/02/17 03:48:17 geraint
## Use assignment LHS to gather tmp variable names.
## Prevents collection of long expressions, eg: tmp34*(tmp75
##
## Revision 1.27 2001/02/14 06:06:34 geraint
## Removed octave_value_list wrappers from standalone.exe - speed improvements
##
## Revision 1.26 2001/02/05 08:50:58 geraint
