Over here Matrix<float,3,3,0,4,4> does not even compile but let's
assume we used Matrix<float,Dynamic,Dynamic,0,4,4> ...
I think it is ok, that Matrix behaves as it does right now, i.e. I am
fine with what is happening here
Matrix<float,Dynamic,Dynamic,0,4,4> m(3,3);
m << 1,4,7, 2,5,8, 3,6,9;
std::cout << m << std::end;
1 2 3
4 5 6
7 8 9
What is unfortunate is that this shows me right away that I have a
huge bug in conservativeResize for stack objects...
m.conservativeResize(4,4);
std::cout << m << std::endl;
.... rubbish ...
So there is some work to do.
Back to the topic. What Gael proposes sounds like stride support in Matrix...
