Hi there,
unfortunately I have only a solver licences from my UNI for the 23.7 GAMS release.
In the installation set up of that version, I cannot tick “advanced options” to add GAMS directory to PATH environment variable
Somehow MATLAB does not find GAMS
This is the message if I write: system ‘gams ? lo=3’
‘gams’ is not recognized as an internal or external command,
operable program or batch file.
In the meantime I tried to install 24.1. version to communicate between the 24.1. version and GAMS, but that’s stupid - I would like to control my licenced version with MATLAB…
Has someone an idea?? I can also not find instructions on the GAMS homepage…
Stefan

Hi Stefan
You can easily add the path to the system variable (see here http://www.computerhope.com/issues/ch000549.htm for how to do this).
If you don’t have the rights to do this, you could add this directory temporarily using a batch file like this:
echo %path% > path.txt
SET PATH=%PATH%;c:\whatever\else
The first line saves the existing path environmental variable in the file path.txt (Windows or I once deleted this variable with all the directories for the executables, and I was happy to have a backup).
The next one adds your directory to the existing path. Save this lines in a batch file (e.g. mypath.bat) and double click on it.
Hope this helps
Cheers
Renger

Hi thank you very much!
I figured out how to set the path environment variable…
Nevertheless - the MATLAB2 GAMS tool is unfortunately buggy with the 23.7 release - It gives several errors, which cannot track down… So I try a work around…

hi there,
I am facing quite the same problem with Gams. I have added the GAMS to the PATH environmental variable (C:\GAMS\win64\24.1;C:\GAMS\win64\24.1\gbin) and i have done it also in the set path option in MATLAB (C:\GAMS\win64\24.1). The problem is that when i type a command like ; system ‘gams ? lo=3’ or something similar i get the message " ‘gams’ is not recognized as an internal or external command,
operable program or batch file. ",
whereas when i type “which gams” in command window I get this “C:\GAMS\win64\24.1\gams.mexw64”
What can i do?
