recursive action into folders

I wanted to do mcc to all the files inside the folder... you know automate it.
This one does it!

clear all
clc
% Read directory names
dirLIST = dir

% get number of directories
N = length(dirLIST)

% Loop through the directories
% Skip the first two..
for n = 3:N

 
    thisDIR = dirLIST(n).name;


        cd(thisDIR);
         disp(['Working on ' thisDIR]);
        mcc -m run_me_deAR.m

        pwd

     
 cd('..');


end
