​my cosmetic and artistic opinion about that:
​
​with ublas, you can do that:​

​#include <boost/
​numeric/ublas/matrix.hpp>

// this is not needed but it's useful to have them
​#include <boost/
​numeric/ublas/io.hpp>
​#include <boost/
​numeric/ublas/assignment.hpp>

​int main()
{
    fixed_matrix<double,3,3> m1;

    m1 <<= 1,2,3
           4,5,6,
           7,8,9;

    cout << m1 << endl;
}

And personally, I find fixed_matrix<double,3,3> to be easier to remember
and more explicit to use than floatvec2 or dblmat2x2 or whatever else. And
I don't have to look into the doc, if I can't remember if the matrix name
was DblMat2x2 or double_mat2_2... or Matrix2D ? (no, it's not the same
library).
