## Function Documentation

function Th = SquareMesh | ( |  | N | ) |

Initialization of the Mesh structure for a square domain.

Square domain is .

This mesh has 4 boundary labels
  - label 1 : boundary
  - label 2 : boundary
  - label 3 : boundary
  - label 4 : boundary
    There are N+1 points on each boundary.

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