Hi Steve,
Thanks a lot for the info.  I saw that but did not know exceptions
were disabled in some compilers by default, which as you suggested, I
found out this one does.  I enabled them, and now it compiles.

I have another question for you if I may.  I attempted to simply
stream the numbers to the standard output but it complains that there
is no operator defined for this object.  Is there a file I can include
that contains the overloaded output operator functionality?  I am sure
this must be available, I am just not sure of its location.  I know
that ublas uses the file "IO" in order to bring those definitions in.

Again, thanks for everything and have a good one!
