What do you mean? Do you need to remove those two in order to compile?

Yes, I think they can be removed. Any objections?

(Or we should add them to the GenericMatrix interface.)

It would break the ODE solvers since they assume the uBlas interface.
Since uBlas is fairly standard, part of boost, just a collection of
header files and is part of Debian, it's generally not a problem to
rely on uBlas.
