		me,
		areas,
		lambda,
		mu
	)

Global Computation of the element stiffness elasticity matrix. Block numbering.

Parameters:

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 $\q$ , $\jl\in\{1,2,3\}$ and $k\in{\ENS{1}{\nme}}$ .
areas	Array of areas, $1\times\nme$ array. areas(k) is the area of the -th triangle.
lambda	the first Lame coefficient in Hooke's law
mu	the second Lame coefficient in Hooke's law

Return values:

Kg	$36\times \nme$ global element stiffness elasticity matrix
