If C++11 is enabled, fixed-size column or row vectors of arbitrary size can be initialized through a single initializer list (\link Matrix::Matrix(const std::initializer_list<Scalar>&) details \endlink):
If C++11 is enabled, fixed-size column or row vectors of arbitrary size can be initialized by passing an arbitrary number of coefficients:
\code
Vector2i a {1, 2}; // A column vector containing the elements {1, 2}
Vector2i a(1, 2); // A column vector containing the elements {1, 2}
Matrix<int, 5, 1> b {1, 2, 3, 4, 5}; // A row-vector containing the elements {1, 2, 3, 4, 5}
Matrix<int, 1, 5> c {1, 2, 3, 4, 5}; // A column vector containing the elements {1, 2, 3, 4, 5}
Matrix<int, 1, 5> c = {1, 2, 3, 4, 5}; // A column vector containing the elements {1, 2, 3, 4, 5}
\endcode
In the general case of matrices and vectors with either fixed or runtime sizes,
