I'm working with the MATLAB program on macintosh to itterate transition matricies for plant populations (american ginseng) right now our system is locked due to errors even the MATLAB people haven't seen. We're working on getting it sorted out, but if anyone has worked with the program and could send me a list of problems or things to avoid whenI'm programing my m-files i'd surely appreciate it. Or if you have any suggestions as to what other programs work well with populations synamics modeling. thanks....you can post or e-mail me at remer@unoma1 remer@zeus.unomaha.edu or you can try lawson@ksuvm as a last resort.(our mail system at uno is really buggy right now. lynne remer (lab slave)

Both Theorist and Mathematica handle matrices well. Also there is a wonderful program/simulation environment called Extend by Imagine That Inc. I started a model in that environment to look at the population dynamics of Chamise (Adenostoma fasciculatum). This is a block oriented simulation environment. It allows stuff (including matrices/vectors) to flow from one block to another. This may be a better environment once you know what the transition matrices are and you want to see what they will do to various initial populations. -- Jeremy -- Biophysics Brandeis University
