Hi: I just thought I would put this information out, since a new college semester will begin soon. Hopefully this info will spare folks the cost of having to buy proprietary M$ software for their coursework. It's been my experience that some prof invariably wanted me to use MathCad or Sigma Plot for his/her class. Any way here is the line up: GNUPlot: comes on the SuSE CD's. Does an excellent job of plotting and will do curve fitting. Plots can be saved in postscript or *.png format. A very good short tutorial is here: http://www.duke.edu/~hpgavin/gnuplot.html. The general web site: http://www.gnuplot.org/ XGFE: The GUI front end for GNUPlot. On the SuSE Pro CD's. Can be downloaded from: ftp://ftp.suse.com/pub/suse/i386/7.2/suse/xap2 OCTAVE: A high level programming language Like MatLab. On SuSE Pro CD. Or you can get the g77 RPM here: ftp://ftp.suse.com/pub/suse/i386/7.2/suse/d2, load the development libraries from your SuSE CD's (Pro or Personal) and then compile Octave in. Compiliation makes for a slightly faster running Octave. The download and on line tutorial are here: http://www.octave.org/ NOTE: Octave requires GNUplot to run; so install the GNUPlot rpm before compiling. Octave is *really* good. Scilab: Another high level programming language Like MatLab. rpm on SuSE pro CD's or from here: ftp://ftp.suse.com/pub/suse/i386/7.2/suse/xap2. Scilabs instruction are a bit difficult to understand; they are very terse. The graphics are excellent. HTH. -- Cheers, Jonathan
