I agree on your stand about matrix vs vector types as being distinct, but 
I don't agree that a matrix is just composed of rows of elements. It could 
also be columns of elements. Which is it? A matrix should be left as a two 
dimensional array (conceptually), either row-major or column-major or the 
exact layout could be a parameter, as for boost::multi_array, except this 
time maybe as a template parameter.
