fix_c.r called at ese2rdae stage so that pow gets fixed in ae.r. check-in: 9f3e8d8749 user: geraint@users.sourceforge.net tags: origin/optimise-algebraic-equations, trunk
11:14:51
ae.r now generated using def2write_r like cse?.r
fix_c.r called at ese2rdae stage so that pow gets fixed in ae.r.

These changes produce the desired result (optimised algebraic equations) but
have highlighted a problem; when optimisation fails, Reduce does not write
a result. For complicated systems, this can lead to missing assignments in
the resultant code. check-in: cc69033e71 user: geraint@users.sourceforge.net tags: origin/optimise-algebraic-equations, trunk

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.
check-in: dc3ec712bc user: geraint@users.sourceforge.net tags: origin/master, trunk
14:48:34
Inclusion of sympar.h moved to top of file for consistency with other templates.

states and outputs prepended with an underscore to prevent conflicts when
inputs and outputs have the same names. check-in: 373df68651 user: geraint@users.sourceforge.net tags: origin/master, trunk

10:36:21
Fix for bug [553524] #define PI causes parse error.
Only substitutes for PI if it is not a number. This prevents Reduce from
trying to substitute for 3.14... when "on rounded" has been set.

`mtt sys sfun zip` now produces an input block and an interface block for MTT models.
Models can be embedded within larger Simulink models by the 2 ports.
The user must edit 2 code blocks in <sys>_sfun_interface.c before compiling with mex.

MTT input block "sys_sfun_input.mexglx" created to provide inputs from MTT input file to plant model within Simulink.
The command "mtt sys sfun zip" now also creates a simple sys.mdl file which connects the input block to the plant block correctly.

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. check-in: 97bf211b88 user: geraint@users.sourceforge.net tags: origin/master, trunk
