My turn: 1. Both Maxima/XMaxima/wxMaxima and R run on my XO out of the box courtesy of "yum". With the Maximae, you get your choice of Lisp run times. I've successfully used both the clisp and SBCL runtimes. They do have a lot of dependencies, however, so watch your flash space. 2. Maxima is a Computer Algebra System and R is a graphical and statistical/numeric package. Both will do "number crunching", but they're two different beasts, and both fundamentally different beasts from Matlab. 3. There are two and a half "free Matlab clones". Someone mentioned Octave, but there is also Freemat, and a "half-free" package called SciLab. I call SciLab "half-free" because I don't know its exact license. You can download it freely, but I'm not sure all of the GPL freedoms are in place on it. I have used exactly none of these -- I learned R and don't see the need for another number cruncher. 4. On to Sage -- Sage is a wonderful package. It is written in Python and wraps many specialized and more general math packages. Its goal is to replace Mathematica, Maple, and some other less-well-known math packages. However -- it's huge. And it installs everything independently of whether you have the same package already as part of your distro. I loaded it once, but there were only two or three rather specialized packages in Sage that weren't in my Gentoo repositories already. I think it's modular -- you don't have to load the whole enchilada. I might load the base on my virtual XO just to see how much space the core takes, because it's really an excellent collection. If you can only load *one* math package, I highly recommend wxMaxima with the clisp run time. That's going to give you the most bang for your flash space. You don't really need XMaxima -- wxMaxima is a much better UI. By the way, wxMaxima also runs on Windows!!!!!!!!!! Well ... so does R. In fact, the Windows UI for R is better than the core Linux UI. :) _______________________________________________ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
