If you can't use DDE23 because you're using a very old version of MATLAB (DDE23 was introduced in release R13 over 11 years ago) or because you're using a different package that doesn't provide DDE23, you could try implementing a DDE solver on your own using the references and notes on this Wikipedia page:
