Is it possible to programmatically run and export a live function in MATLAB Version R2020a? I know in version 2022 you can use the export function.

I know that in Matlab 2022, you can use the function

export("MyLiveScript.mlx");

to export a Live Script or Function. But this doesn't work in Version 2020. Is there any work around, other than just clicking the menu bar?

As per my understanding, you want to programatically execute and export a livescript. For MATLAB version R2020a, please look at the following commands as a possible workaround solution to run and export live function- MyLiveScript.mlx

mlxloc = fullfile(pwd,'\MyLiveScript.mlx');
fileout = fullfile(pwd,'\test.docx');
matlab.internal.liveeditor.executeAndSave(mlxloc);
matlab.internal.liveeditor.openAndConvert(mlxloc,fileout);

It shall convert the live script to a docx file and save it in the current folder. To save the output file, you can here use file extensions as per your convenience.

That looks like what I want to do. However, I get the following error:

Error using matlab.internal.liveeditor.LiveEditorUtilities.open>openUsingCEF (line 119)
Java exception occurred:

Yes, It works now. The problem was that I needed to call your code from a separate mfile! Thanks for the help!
