for many tasks, gnu octave (a 'matlab clone', no offense to gnu folks intended) is quite sufficient, and *free* (+ open source). you can run some of matlab code in octave.
you should also check if sage (http://www.sagemath.org/) can do the job for you, it's stuffed with all sorts of maths utilities, with friendly python frontend, etc. and once you're at python's, check numpy, scipy, and matplotlib, which do lots of good work too. all open source, of course. vQ Clint Bowman wrote: > The easy way around that is to create an account, "Mathworks", with a > common group that all who will use MatLab belong, then su - Mathworks > should satisfy the license manager. > > Clint Bowman INTERNET: [EMAIL PROTECTED] > Air Dispersion Modeler INTERNET: [EMAIL PROTECTED] > Air Quality Program VOICE: (360) 407-6815 > Department of Ecology FAX: (360) 407-7534 > > USPS: PO Box 47600, Olympia, WA 98504-7600 > Parcels: 300 Desmond Drive, Lacey, WA 98503-1274 > > On Fri, 20 Jun 2008, Earl F.
