function Th = SquareMesh ( N )

Initialization of the Mesh structure for a square domain.

Square domain is $[0,1]\times[0,1]$ .

This mesh has 4 boundary labels

Generated fields of mesh structure: q: Array of vertices coordinates, $2\times\nq$ array.
${\q}(\il,j)$ is the $\il$ -th coordinate of the -th vertex, $\il\in\{1,2\}$ and $j\in\ENS{1}{\nq}$ me: Connectivity array, $3\times\nme$ array.
$\me(\jl,k)$ is the storage index of the $\jl$ -th vertex of the -th triangle in the array $\q$ of vertices coordinates, $\jl\in\{1,2,3\}$ and $k\in{\ENS{1}{\nme}}$ . ql: Array of vertices labels, $1\times\nq$ array. mel: Array of elements labels, $1\times\nme$ array. be: Connectivity array for boundary edges, $2\times\nbe$ array.
$\be(\il,l)$ is the storage index of the $\il$ -th vertex of the -th edge in the array $\q$ of vertices coordinates, $\il\in\{1,2\}$ and $l\in{\ENS{1}{\nbe}}$ . bel: Array of boundary edges labels, $1\times\nbe$ array. nq: total number of vertices, also denoted by $\nq$ nme: total number of elements, also denoted by $\nme$ nbe: total number of boundary edges, also denoted by $\nbe$ areas: Array of areas, $1\times\nme$ array. areas(k) is the area of the -th triangle. lbe: Array of edges lengths, $1\times\nbe$ array. $\lbe(j)$ is the length of the -th edge.
