How rename files with loop

Hello I constructed a loop with witch I created one file per iteration :

example :

subject = {'1' '2' '3'....etc};

for i = subject
    with_my_procedure_I_created_myfile = A
end

I would like in each iteration that myfile "A" can be rename by :

A1 for the first iteration

A2 for the second

A3 for the third ... etc

How can I do ???

One way, e.g.,

>> names=arrayfun(@(i)['A' num2str(i)],1:5,'un',0)

names = 

      'A1'    'A2'    'A3'    'A4'    'A5'

and then of course

 for i=1:length(names)

    thisname=names{i};

 end

Use sprintf() like the first code block in the FAQ shows you: http://matlab.wikia.com/wiki/FAQ#How_can_I_process_a_sequence_of_files.3F

In the loop, create your input and output filenames, then use movefile() to do the renaming .
