| This Introduces the three fundamental types of PDE's -- Elliptic, Parabolic and Hyperbolic and studies the numerical solution of Elliptic Equations |
| The sparse matrix formulation is used and iterative approachs -- Jacobi, Gauss Seidel and SOR are defined |
| These are motivated by analogies between equilibrium of diffusive equations and elliptic systems |
| Eigenvalue analysis is used to discuss convergence of methods |
