Hello,

I have a question about a code. I have a .m script. This script requires 2 inputs in a folder in order to run. But I would like to run this .m script for all folders in a directory (path). The reason is that each input has different numbers so different results of each run of .m code will arise.

Could you please help me?

Why are you using scripts? This would probably be easy with a function that accepts a path.

if i understood you correctly your script simply works in the current directory. what you can do is that you add your script to your search path ( addpath() ) and then navigate to the folders using cd() and calling your script

ok Bbut my point is that if I could do it in an autimated manner. I would like to use some commands that will seach one to one my folders and run my script for each folders.

Is there a way to make it?

在 MATLAB Online 中打开

e.g. if all folders in which you want to run the script are on the same director level you could use something like

addpath('MyScript.m')
dirContent=dir(); % get content of current directory
dirContent(~[dirContent.isdir])=[]; % delete entries that are no folders
dirContent(1:2)=[]; % delete '.' and '..' directory
folders={dirContent.name} % get folder names
for dirNr=1:numel(folders)
    cd(folders{dirNr}); % change dir to specified folder
    MyScript();
    cd ..; % go back up a level
end

NOTE: this loop should not be changed to a parfor loop because changing directories causes some issues in that case

You really should avoid messing with the path only to read/process files.

You should convert your script to a function that accepts a path. If you need help with that, feel free to comment with your issues. If you attach your script to a comment we may be able to give you more targeted advice.
