tricoefCal

Compute the coefficient matrix <code>tricoef</code> required to test
if a point is inside a triangle.

Finite element modeling (FEM) uses meshes of triangles to define surfaces.
A surface within a triangle may be either linear or quadratic.
In the order one case each node in the mesh is associated with a basis
function and the basis is called the order one finite element basis.
In the order two case each edge mid-point is also associated with a basis
function. Functions are provided for smoothing, density function estimation
point evaluation and plotting results. Two papers illustrating the
finite element data analysis are Sangalli, L.M., Ramsay, J.O.,
Ramsay, T.O. (2013)<http://www.mox.polimi.it/~sangalli> and
Bernardi, M.S, Carey, M., Ramsay, J. O., Sangalli, L.

spatial anisotropy via regression with partial differential
