Subject: [ublas] storing matrix proxies, uninitialized rows

Apologies for the novice nature of the question, but I haven't been able
to find an answer, likely due to not knowing how to phrase it.
Is it possible for one object to store a proxy/slice/row reference to
part of a matrix owned by another object? i.e. I'd like to have
something like:
using namespace boost::numeric::ublas;
class A{
matrix<double> Mat;
B foo;
};
class B {
matrix_row<matrix<double> > R;
void SetRow( matrix_row<matrix<double> > rowin ){R=rowin;}
};
such that class B can modify it's part of the matrix contained in A, and
A can modify the same matrix which B's proxy sees?
Thanks in advance.
