Can someone provide a simple example of how a list of N elements can be
generated, with the list elements being normally distibuted? I'd like to
include random seeding so I can generate an ensemble of such lists.
Are there general tools in Mma 3.0 for generating lsits with various
statistics? How do I go about searching for sites where these kinds of
tools can be found?
Thanks.
