laplace_radial_exact, a Fortran90 code which evaluates exact solutions u(x,y) or u(x,y,z), with radial symmetry, to the Laplace partial differential equation (PDE): del^2 U = 0.
The solution functions are defined over the whole domain, except for a singularity at the origin, because of the occurrence of a term involving log(R) or 1/R^n, where R is the distance to the origin.

f90_exact, a Fortran90 code which evaluates exact solutions to a few selected examples of ordinary differential equations (ODE) and partial differential equations (PDE).
