How could I save a file under different name?

 if true
    files = dir('*.csv');
 for f = 1:length(files)

    file = files(f);
    RawData=importdata(file.name,',',4); 
    MusAct=RawData.data;

    title = file.name;
    new_title = strrep(title, file.name, file.name+'HoldPCA');
    dlmwrite(new_title, mean3tr,'delimiter',',','-append');

 end
 end

I have files that I modified and I want to save them under different names. For example, if an original file name is 'filename.csv', I want to save it as 'filename_Mean.csv'. I want to save as a file, and then move to the next file.. How could I do this? Could I do this in a loop?

Use movefile() to rename a file.

Use copyfile() to copy a file.

See the FAQ for code examples about processing files in a loop: http://matlab.wikia.com/wiki/FAQ#How_can_I_process_a_sequence_of_files.3F
