You find a lot of submissions for searching in folders recursively:

http://www.mathworks.com/matlabcentral/fileexchange/?term=dir+recursive

E.g. this submission has a lot of votes: FEX:enhanced rdir

You get a list of file names with paths. Now create a loop over these file names and use movefile or copyfile to write them to the wanted location. The functions fileparts and fullfile might be useful.

recurse_subfolders.m

See my attached demo, which uses genpath().

Of course you could always just make up your folder names with sprintf() if they have names that are known in advance, and then use the FAQ http://matlab.wikia.com/wiki/FAQ#How_can_I_process_a_sequence_of_files.3F, but the genpath() method is better if you don't know the folder names in advance.

i want to make an array of those files which are listed in command window so i can run my code in single loop for all those files. could u help me.

 how to put all files in one folder or in one array.
i just started using matlab 3 weeks ago.

Sorry I saw this late, but it looks like you've accepted an answer so I assume you have this solved and this comment is not relevant anymore. Besides, I didn't understand the question anyway or how the FAQ doesn't answer it.
