Triangle quality measure

q = pdetriq(p,t)
q = pdetriq(p,t) returns
a triangle quality measure given mesh data.
The triangular mesh is given by the mesh data
t. For details on the mesh data representation,
The triangle quality is given by the formula
where a is the area and h1, h2, and h3 the side lengths of the triangle.
If q > 0.6 the triangle is of acceptable quality. q = 1 when h1 = h2 = h3.
