I just upgraded to MATLAB r2019a and I cannot execute commands in Matlab from Lumerical anymore.
I followed all the steps in https://kb.lumerical.com/install_matlab_integration.html, Matlab integration status is green,the ActiveX test worked fine, and I also performed !matlab /regserver.
In Lumerical, I type “matlab(‘1’);”, for example. I see the Matlab command line opening up in the windows taskbar, but then it disappears, and I get the error:
Can not open a connection to MATLAB. You must have a supported version of MATLAB installed to use this feature. Please see the manual for details
I also checked the other two posts on your forum,
which are not helpful. Can you advise?
