I realize now this statement only partially true. The graphic
is different (it is missing some connections), but it
is reproducible. I overlooked the random number generation
in my file. If you set the random numbers in Mark's
program like this:
cx = randomu(-3L, [np])
cy = randomu(-10L, [np])
Then you can see the missing connections near the
top of the plot.
Sorry for the confusion.
Cheers,
David
