Running an m-file in each subfolders

I'm looking for away to access subfoders and run script ('TESTING_4000.m') in each subfolder. Not sure what I'm missing in the code.

if true
  % code
folder  = 'C:\Deterministic\New Objectives_Log';
list    = dir(fullfile(folder,'Log_4000*'));
nFile   = {list([list.isdir]).name};
C       = cell(1,numel(nFile));
for k = 1:numel(nFile)        
  C{k}          = run(fullfile(folder,nFile{k},'TESTING_4000.m'));  
end
end

Can anyone help please.

run does not return any output arguments.

i just want to run the mfile for each subfoder and I'm using save in the mfile to save the vectors I need. Do you have another way you recommend?

HI Stephen, after the first subfoder was run. The model stopped and showed k value in the for loop is undefined. Is there anyway, I can fix this? Thanks

" Do you have another way you recommend?"

Yes: write functions rather than scripts, return the data that you need in output argument/s, save that data.

"after the first subfoder was run. The model stopped and showed k value in the for loop is undefined. Is there anyway, I can fix this?"

You did not show us any code, so we have no idea what your scripts are doing. Possibly you used clear in your code this causes existing variables to be cleared. Solution: do not use clear in any script or function. But until we actually see your code we can only guess, and debugging by guessing is very inefficient.

Thanks Stephen for all the ideas and help. It is working finally.

I just updated the code and it is working now thanks.

run(fullfile(folder,nFile{k},'TESTING_4000.m'));
