Well, looking at the actual list of functions on octave packages I can see that frontcon and portalloc are not available yet. If you need them, writing them might be a good place to start contributing. I know nothing about money (I'm just a biologist that does some image analysis). Sometimes the reason they don't exist is because they're really simple things, 3-4 lines of code using the other functions of the package (I know that happened for me) so don't be put off by some missing functions. You'll probably be most interested in the financial and statistics package. > Next I will start with installing/building/using Octave (maybe some > toolboxes only) and would much appreciate it if you or others could give > suggestions. To install octave, most linux distros would already have it on the repositories or you can compile it yourself (download it from here http://www.gnu.org/software/octave/download.html). If you want to compile it yourself try to do it first and ask if you have a problem (though that should be asked in the octave-help mailing list of octave core) > Also, which Octave-related mailing lists should I attend? Aside this maling list for octave-forge, there's also octave-help and octave-maintaners (http://www.gnu.org/software/octave/archive.html) Carnë ------------------------------------------------------------------------------ EditLive Enterprise is the world's most technically advanced content authoring tool.
