Vectors of small dimension
==========================


In spaces of small dimension, such as :math:`\mathbb{R}^d` with
:math:`d = 1,2,3`, vector calculus is performed with the class
``SmallVector``. In particular, vertices of meshes are systematically
considered as points of :math:`\mathbb{R}^3`, even for 1D or 2D
meshes, and are modelled by objects of type ``SmallVector<double,3>``.
