No site license for matlab here - I generally have my students couple
gnuplot with some sort of language (perl or fortran depending on how long
the job will run), or offer mathematica as an option.

Yes, I agree, there is no more asinine task than matrix calculations in
excel.  I keep waiting for Microsoft to have competent-looking graphs be the
default when plotting x&y data.  The new version it even worse than  XP
excel.  The plots are rendered with some sort of open GL surface so that
trend lines now look like giant ropes of licorice.
