 E-mail woodchips@rochester.rr.com.removethistosendmemail Company/University Retired Personal Profile Mainly retired from Eastman Kodak. (Of course, Kodak itself is now semi-retired. I don't think I had any influence in that.) I still write MATLAB code as I find something interesting, and I do attempt to write new tools to put on the File Exchange when I think I can make a contribution. However, I DON'T answer direct e-mail questions, and I do NOT do homework. In general, your homework is YOUR problem, not mine. Please do NOT e-mail me with your homework problems or student projects. If I was willing to answer your questions, I would very rapidly become overwhelmed, because one question is never just one simple question. When I'm not doing something with MATLAB, you might find me playing bridge, either in the club or online on BBO. Professional Interests: MATLAB, numerical analysis, mathematical modeling Avocational interests: Bridge, woodworking, woodturning Professional Interests Bridge, MATLAB, numerical analysis, mathematical modeling
