Hans Petter Langtangen coauthored a text on finite difference methods for partial differential equations with Svein Linge. Its treatment of diffusion equations derives discrete updates and investigates their stability. The connection between an explicit Euler method and a spatial second-difference operator makes the restriction on the time step visible in a reproducible computational model.[ref]
