I just installed Octave, will have to see if that will work.  Was playing
with Scilab a bit earlier, and it might work too.  I've just got to figure
out how to use these, and process a set of data before Christmas.  It
might be just about as easy to hack together a Python program, will have
to review the autocorrelation function here to see ...
