Subject: [ublas] vector_of_vector?

I have not used ublas in a while, so sorry if my questions are trivial.

I need a data structure, Dat, that is like vector of vectors and that I
can use in combination with boost/range.hpp 's functionality. For example:

typedef range_value<Dat> range_;
typedef range_value<row_> elem_;

Dat_ dat; //fill
elem_ e22 = next(next(begin(dat),2),2).

I though vector_of_vector would do it, but apparently not. I'd like to
hear your suggestions. Thanks.
