I have an issue which I think is a result of my lack of understanding of how relative paths work in Matlab and I was wondering if someone could help me. Effectively, I have an Matlab executable (.exe) that I want to run from my own code.
Basically my folder structure is the following:
MyProject/
MyCode/
ThirdPartyMatlabModel /
MatlabModel.exe
Data /
The data ingested by the model
If I run MatlabModel.exe from windows explorer everything works fine and the model works.
However when I try to run the executable from the my code I end up with the following error messages.
Error using textscan
Invalid file identifier. Use fopen to generate a valid file identifier.
Error in parseINI
MATLAB:FileIO:InvalidFid
Does Matlab take relative paths from where the EXE is run from?
Does anyone have any suggestions as to how to rectify this issue?
Thank you for any response.

Wouldn't this be easy to check by inserting a dialog box that displays the pwd?
One thing you could try is using the mfilename function to find the location of your exe. I don't know if that would work, but it is worth a try.

Unfortunately I don't have access to non-obscured Matlab source code. I only have access to the EXE and the folder with the ingested data. I should be able to get in contact with the third party, it will just take a bit of a time and bottle necks my work. So I guess I'm also trying to understand the issue further, to see if there is something on my side I can fix or if I have to message them.

"Does Matlab take relative paths from where the EXE is run from?"
Only if it was created as a console application and you are running it from inside a terminal window.

Thank you. I'll need to get in contact with the source and see if I can get them to rebuild it.
