How to add files to other parallel pool?

when I load a mat file before the parfor circle , I get an error described below. An UndefinedFunction error was thrown on the workers for 'm_nDeteDirect'. This might be because the file containing 'm_nDeteDirect' is not accessible on the workers. Use addAttachedFiles(pool, files) to specify the required files to be attached. See the documentation for 'parallel.Pool/addAttachedFiles' for more details.

And then I add two lines of code to addAttachedFiles according to the error.But still get the same error.The code is in the attached file(test.m).
