1. An example is given in gmmstart.exa, gmmh.exa, gmmhc.exa. These files should be copied to gmmstart.m, gmmh.m, gmmhc.m respectively. The data set corresponding to this example is hs82data.dat. Translate this to a .mat file if one does not already exist. 2. When set up, just type "gmmstart". 3. I have included a file "numder.m" for calculating numerical derivatives (i.e. in gmmh.m) if needed. 4. The documentation is in gmm.tex, a TeX file. 5. If there are any problems, you can call me at 919-684-2439 or send mail to erm@egrlab.ac.duke.edu. 6. If you send me an internet address, I can send relevant information (i.e. bugs, updates). Ellen
