....and 800 MB * 4 = 3.2 GB  (Attention, I have expressly said 4
matrixes ).
 What type of matrixes? I hope is not those all of 0 as you had
already told me in another newsgroup (sci.math.symbolic). Test please
using Table and an expression of the single element an a little more
complicated (or that from me suitable): it would interest me to know
the result in this case.  
However, for the precision and correctness I have not verified on Mac
but only on WinXP and Linux.  

However thanks of the help. 
Cordiality
