I tried to use this code to export multiple files in a folder, but it's not working:

Publish() works fine, but not export whose format I want.

clearvars
dirName = 'C:\Users\User\Desktop\NeedToExport\'
addpath(dirName)
files = dir(fullfile(dirName,'*.mlx'))   
files = {files.name}'                    
for i = 1:length(files(:,1))
    dirName = 'C:\Users\User\Desktop\NeedToExport\'
    % This one is because the scripts have clearvars at the front and
    % clears my variables for filenames
    files = dir(fullfile(dirName,'*.mlx'))   
    files = {files.name}'                    
    filename = files{i,1}
%     filename = append(dirName,files{i,1})
%     filenamepdf = append(filename(1:end-3),'pdf')
    filename = convertCharsToStrings(filename)
%     filenamepdf = convertCharsToStrings(filenamepdf)
    path = export("Test.mlx")
    path = export(filename)
end

If you create a new function to do the export() call, and pass the filename into that function, then any clearvars would only affect the workspace of the function, leaving your controlling script alone. You would still have a problem if the scripts contain clear all though.

@Walter Roberson Thank you for the comment, but the main problem is the export() call doesn't work. Could you please tell me what did wrong? Publish() works fine, but it does not give the format that I want.

The tooltip says I need "obj", "rtcId", and "Options". I assume obj is the file name, and options is optional, but I cannot find any information about "rtcId".

在 MATLAB Online 中打开

files = dir(fullfile(dirName,'*.mlx'))

You use the folder information when you do the dir() but you only extract the name part of the result. You do not add the folder information onto the file name that you pass to export()

I still get "Check for incorrect argument data type or missing argument in call to function 'export'.".

What do you get if you ask

which export("test.mlx")

According to the Version History at the end of its documentation page, the export function that will "Convert live script or function to standard format" was "Introduced in R2022a". The release information on the right side of this question indicates you're using release R2021b. You will need to upgrade to release R2022a (or later, if you're reading this after release R2022b is released) to use this function.
