 What is this?
  Author: Jacek Kierzenka
  Summary: Solving delay differential equations with DDE23. Tutorial + Examples.
  MATLAB Release: R13
  Description: This tutorial shows how to use the MATLAB solver DDE23 to solve delay differential equations (DDEs) with constant delays. The solver is available in MATLAB 6.5 and later.

The tutorial briefly discusses the differences between solving ODEs
and DDEs, and describes the techniques used in DDE23. The capabilities of the solver are illustrated by several realistic examples.
Additional exercises and problems are provided for practice. The codes that solve all the examples, exercises, and problems can be found in the directory DDE_examples.
The directory DDE_examples_70 contains the files for all the examples exercises, and problems, updated to take advantage of features available in MATLAB 7.0 (R14).
More information about solving DDEs in MATLAB, can be found in the paper

Appl. Numer. Math., 37 (2001), pp. 441-458.
