### Function Reference: `bim1a_axisymmetric_reaction`

Function File: [C] = bim1a_axisymmetric_reaction(mesh,delta,zeta)

Build the lumped finite element mass matrix for a diffusion problem in cylindrical coordinates with axisymmetric configuration.

The equation taken into account is:

delta * zeta * u = f

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