Hi,

I'm calling some functions in a .NET assembly that is in a different folder to MATLAB. I'm aware that using dllimport for unmanaged DLLs doesn't work in this case because matlab.exe is in a different folder. Copying the unmanaged DLLs to the MATLAB installation folder works, but this is not an ideal solution for production code.

Is there a way to get around this problem without hard-coding directories? I'm trying to avoid editing the Windows path.

Thanks

James

Hi,

you can edit the PATH locally for MATLAB only with the setenv command:

setenv('PATH',[getenv('PATH'),';C:\your folder with DLLs'])

So you can build up the PATH dynamically at runtime and set it silently in the background.

UPDATED TYPO (Thanks James)

Thanks very much! Though I used

getenv('PATH')

instead of

get('PATH')
