I am able to help identify the source of Generic_Real_Arrays.  (At
least I know the source of *one* such library.)

I have a collection that has several numeric math packages, and one
from Drexel University contains Generic_Real_Arrays.Operations.

Now that I review this item, I discover that this package defines a
subprogram "Singular_Value_Decomposition".  By golly, that is the
answer to another recent posting as well!

You can acquire the Drexel U Matrix Math items from  
http://dflwww.ece.drexel.edu/research/ada/
They are marked:

-- $AUTHORS: Chris Papademetrious, Xiaoxun Zhu, Moshe Kam

BTW I am just completing a library that is useful for programs that
want to perform IO operations for numeric applications.  I'll be
seeking a venue for making this stuff publicly available within the
next few days.  Suggestions and early-look testers welcome....
