The program DLA_GUI has been written to carry out the computations associated with demographic loop analysis as described in  using MATLAB Release R2008a with the Optimization Toolbox. It runs with an easy-to-use graphical user interface.
The read-me file describing the computations carried out by the program can be found Read_Me. The program files (along with the read-me file and standard copyright language) can be downloaded in the folder DLA.zip.
Much of the code was written by Jonathan Vollmer, a computer science major at Truman State University. He has my heartfelt appreciation and respect for his work on this project.
