Thanks for the notebook, Selwyn.

Since my original post I have discovered the SLEIGN2
fortran package and ported the regular case to Mathematica.
It works fine so far on my application.

A good project for somebody's graduate student would be
to port the whole thing -- given Mathematica's superior
visualizations, I very surprised this hasn't been done.

I am also surprised there are no built-in methods for
this, given its importance to mathematics.

alan
