If the image is not working for you, when I use the line “h = appopen(‘fdtd’);”, matlab returns: “Error using appopen - Unable to launch the requested application”. My matlab integration status is active in lumerical, and the Matlab api folder is in my matlab directory. I am using Lumerical 2019b and Matlab 2017a on Mac OS Sierra, version 10.12.6. Any help would be greatly appreciated!
Have you tried the configuration steps in this KB article:
Do both configuration: MATLAB > Lumerical and Lumerical to MATLAB for macOS
You will have to edit the info.list on your MATLAB installation folder to include the path for Lumerical.
Hope this helps.
