GAMS World Forum

you can try only run "gams('producer1')", in the gms file you have to put some variable or parameter in a gdx file by matout sentence. just read that gdx in the matlab file using "readgdx".

Hello everyone!

I am trying to link Matlab and Gams.
The output of Gams model, which is named 'producer1',is the variable "y" which is a 17x104 matrix.
I type this line in command window:
y = gams('producer1')
It solves thd model but it cant assign the outputs to 'y' and returns this error:
"Number of output argument in Matlab exceed output argument specified in gams"
When I just type this line in command window:
gams('producer1')
the error doesn't appear any more.
Do you happen to help me?
Kind Regards

Hi,

I am trying to use matgam; however, I have got two error:

- "Unsupported data format entered." in response of running testinst example;
- "Number of output argument in Matlab exceed output argument specified in gams" whenever I try to take the output such as x = gams('qp').

The first problem is really serious since I want to give some parameter values before solve the problem. I think it may because of version mismatch.

By the way, I am using Matlab 2012a (64-bit) and the demo version of GAMS release 24.3.3 r48116 WEX-WEI over Windows 7 (64bit).

I would be grateful if you could let me know your comments.

Kind regards,
Arash

Hi Alireza,

Thank you for your reply.

As a matter of fact, there is no new GAMS nor Matlab codes. I just tried to run two GAMS and Matlab test codes available by the matgams package, which are testinst and qp,

Hi
Follow this steps:

1- Have a look to the PDF file i attached you(pages 2 and 7). I had attached all of you need.

2- Add the Gams path to the Matlab

2- Set the environment variable.

Hi Alireza,

Thank you very much for your help.

Actually, I have followed all instructions given by you and the attached pdf and I think I have installed everything properly; however, it still does not work and it generates all previously mentioned errors.

I have solved the problem by changing the gms file directly and parse the generated matsol.gms file including all results, but it is very slow.

Many thanks and kind regards,
Arash

Hi Arash,

I would be grateful if you tell me where I can download the matgam?
If you have this file, please send me to fporras7@gmail.com

Thanks for your attention!

Kind regards,

Semi Off Topic advice: Don't lose sight that the functions wgdx and rgdx for MatLab allow for an easier, more flexible and easier to debug interaction. Of course, running gams from MatLab is also trivial (in my experience).
