the CYGWIN software that has the UNIX utilities. The field as 1000
lines with 10,000 fields on each line. Here is what it reported:

Greg, in light of Doug Bates' question, what i have suggested a little early in
response to your question is known as a Wishart matrix with n degree of
freedom, which is guarenteed to be positive definite. If this is not what you
want, you have to be more specific about the property of this

After multiplication by 10 you get 6*8 = 48 - the
result is an exact machine number so there is no
roundoff, while 0.6*0.8 = 0.48, where neither of the 3
numbers (0.6, 0.8, 0.48) is an exact machine mumber.
However, (-0.6)*0.8 should be equal EXACTLY to
-(0.6*0.8), and in fact you get that
