mfilename not working on Live Editor?

13 views (last 30 days)
Hi. I'm using matlab 2016a. Inside a Live Editor script, I'm trying to get the script name, using the function mfilename, without any parameters, to get it. What matlab gives as an output is: MatlabEvaluationHelper.
I've tried to export this code to a classic matlab .m file, and seems to work fine. Any idea on what could be the problem? Thanks in advance

Hello Jaime,
I am afraid that mfilename does not function inside live scripts or functions. Our developers are aware of this feature request, and are considering possible resolutions for future releases of MATLAB.
Can you describe what you are trying to accomplish with "mfilename"? There may be other ways to get a similar workflow to what you desire.

mfilename still does not work properly in live editor, R2022a. Returns some location on my C drive (while the script is in fact running on a network drive).
However, Jan Kappen idea (filePath = matlab.desktop.editor.getActiveFilename; from 13 Jan 2022) works perfectly. Thanks!

Thank you Jan Kappen for the workaround! and thanks Omit for the +1
After 5 years, it would be nice if the mfilename doc page could be updated to mention the limitation and workaround.
