Hi Wenchao,

I understand that you want to search all the file with a .m extension under one routine.

You could use "dir" function in MATLAB to search for files and directories. Navigate to the top level folder. Then run the following command:

var = dir("**/*.m");
fileID = fopen('element_names.txt','w');
for i = 1:length(var)
    fprintf(fileID,'%s\n', var(i).name);
end
fclose(fileID);

"element_names.txt" would contatin the name of all the .m files in the current folder and within all of its subfolders.

Hope this helps.
