Function File: A = bim3a_laplacian (mesh, epsilon, kappa)

Build the standard finite element stiffness matrix for a diffusion problem.

The equation taken into account is:

- (epsilon * kappa ( u’ ))’ = f

where epsilon is an element-wise constant scalar function, while kappa is a piecewise linear conforming scalar function.
