Here's a list of the matlab codes I've written for doing queueing computations. Please note: these codes evaluate analytic formulas for a few standard models. They do not do discrete-event simulations. I have yet to find a truly reasonable way to do queueing simulations in matlab, but if you have any ideas I'd love to hear them. If you would like a copy, please send me e-mail

You might also be interested in the matlab code written by Rui Kang, posted here.
