Hi,

I need to establish an interface between GAMS and MATLAB. I did all procedures mentioned in the video (https://www.youtube.com/watch?v=HPn_q8nlktE) to interface GAMS and MATLAB. then I tried to test this interface by GAMS test codes. there is a warning sheet that poped up by Matlab as follow.

P.S. The GAMS test code is 'GDXMRW03.gms' . Can you help me to find the problem?

King Regards,

Hi,

I understand that you are facing an issue while trying to test GAMS-MATLAB interface. The error “Unrecognized function or variable” usually occurs when the function or variable is not defined or installed properly.

For more information on these issues, refer to the following MATLAB answer:

To make sure that all paths are configured correctly, you might attempt a reinstallation. The following document provides detailed installation instructions:
