Octave is an open-source equivalent (more or less) to Matlab, although
I'm told the plot functions aren't as good. There's also the R project,
which is mainly used for statistical analysis, although you can do
a great deal else with it. I've also got Gnuplot here, although I
haven't really done much with it.
