Hello,

I have created a script that reads files inside a folder and performs various analyzes.

Each time, I have to go change the directory path and run the script again.

I would like to know if it was possible (perhaps through a for loop of the entire script?) To have the script run for all the various folders in a directory.

See: FAQ: How to access a sequence of files

FolderList = dir('C:\Your\BaseFolder\'):
FolderList = FolderList([FolderList.isdir]);
FolderList(strncmp({FolderList.name}, '.')) = [];  % Remove . and ..
for k = 1:numel(FolderList)
   Folder = fullfile(FolderList(k).folder, FolderList(k).name);
   
   % Now use the Folder to access the files.
end

Prefer to access the files using their absolute path name instead of cd(Folder). Changing the current folder by cd() is fragile, because any callback of a GUI or TIMER might change the folder again during your code runs. Absoulte file names are bullet proof (except if you shoot the bullet into the running hard disk).
