This issue arises directly because of the fact that a matrix conceptually is a compound type, whose components should be acessible to client code. But a matrix is not just a compound type composed of elements. A matrix is composed of rows of elements.
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. -- François Duranleau LIGUM, Université de Montréal
