Then p is a string containing the path of the file, while fn is a struct array, whose element at index z carries the name of the file in the field 'name'.
You can inspect this in the command window: Set a breakpoint in this line and run th function until Matlab stops there. Then:
disp(p)
disp(fn)
disp(fn(z))
disp([p '\' fn(z).name])
