What I really meant to say here is...
The storage type of uBLAS arrays is always a linear array of
consecutive memory locations and can be a std::vector, or one of the
storage types supplied by the library. As such I would presume a
1-dimensional array from the library could be used as the storage type
but I don't see any benefit in using it that way, and in any case I've
not tried. etc,.
