[TRNSYS-users] Coupling MATLAB with TRNSYS

Mon Feb 2 07:36:14 PST 2009

Ali, you may be able to call TRNEXE from the command line, from within
MATLAB.  Here is the syntax as you would write it at the command prompt, or
in a batch program:

> "c:\...\Trnsys16\Exe\TRNExe" "C:\...\Project.dck" /h

I am currently using a Perl script to call both TRNSYS and MATLAB, as well
as modify TRNSYS input files.  The "\h" in the above statement disables the
online plotter and the % completion dialog box.
