Function Documentation

function AElem = ElemStiffMat2DP1	(	q1,
		q2,
		q3,
		area
	)

Computation of the element stiffness matrix for $P_1$ -Lagrange finite elements.

Example

        q1=[0;0];q2=[0;1];q3=[1;0];
        area=1/2.;
        AElem=ElemStiffMat2DP1(q1,q2,q3,area);

Parameters:

q1	Coordinates of the first vertex in the triangle, $2\times 1$ array
q2	Coordinates of the second vertex in the triangle, $2\times 1$ array
q3	Coordinates of the third vertex in the triangle, $2\times 1$ array
area	triangle area

Return values:

AElem Element stiffness matrix, $3\times 3$ matrix
