From what I have been able to gather, I can't figure out whether there is any superclass to all the matrices.. I want to be able to have a list of matrices, some of which may be sparse and some dense... What type should

I am considering using the uBlas library. After a couple of days of researching all available matrix packages for C/C++, I have come to the conclusion that it is the best one in terms of support, ease-of-use, performance(relatively speaking) and documentation. that list be? Or is that impossible (at first glance it appears that inheritance is not really supported for efficiency reasons, hence the widespread templatization)... Thanks in advance for any help.
