By the way, there are a bunch of free tools out there that can be used for this type of problem. I somewhat arbitrarily chose GiNaC because it looked robust (being implemented as a C++ library), but there are many more options that could have done the calculation for free.
If you aren't running Linux but want to play around with some of the free mathematical and scientific tool sets out there, a good way to do it is with the Quantian live-CD linux distribution (based on Knoppix). http://dirk.eddelbuettel.com/quantian.html If you don't know what a "live CD" is : it means you just boot from the CD and you are running the OS from the CD, without having to install the OS on your hard drive. When you are done, just take the CD out and reboot and you will be back running your usual OS on your hard drive (or whatever). -- Erik Reuter http://www.erikreuter.net/ _______________________________________________ http://www.mccmedia.com/mailman/listinfo/brin-l
