The CSE core is required for all CSE students in M.S. and Ph.D. programs. It consists of six one-quarter courses which are distributed over the three areas of numerical methods, parallel computing and applied mathematics.

### Numerical Methods:

A broad-based introductory graduate-level numerical analysis course (CHE 230D/MEE 244D) is available for students who do not have the background to begin the core CSE graduate sequence in numerical methods immediately.

CSE students must take at least three of the following courses. The courses need not be taken in sequence, although it may be advantageous to do so. These courses are cross-listed with Math, CS, ECE and CHE.

#### CS 211/MATH 206/MEE 210/ECEĀ 210 Sequence: Numerical Methods in Computational Science and Engineering

*Prerequisite: Consent of instructor. Students should be proficient in basic numerical methods, linear algebra, mathematically rigorous proofs, and some programming language.*

**210A Matrix Analysis and Computation**

Graduate level-matrix theory with introduction to matrix computations. SVD's, pseudoinverses, variational characterization of eigenvalues, perturbation theory, direct and iterative methods for matrix computations.

**210B Numerical Simulation**

Linear multistep methods and Runge-Kutta methods for ordinary differential equations: stability, order and convergence. Stiffness. Differential algebraic equations. Numerical solution of boundary value problems.

**210C Numerical Solution of Partial Differential Equations Finite Difference Methods**

Finite difference methods for hyperbolic, parabolic and elliptic PDEs, with application to problems in science and engineering. Convergence, consistency, order and stability of finite difference methods. Dissipation and dispersion. Finite volume methods. Software design and adaptivity.

**210D Numerical Solution of Partial Differential Equations Finite Element Methods**

Weighted residual and finite element methods for the solution of hyperbolic, parabolic and elliptic partial differential equations, with application to problems in science and engineering. Error estimates. Standard and discontinuous Galerkin methods.

### Parallel Computing:

CSE students must take the following: CS 240A

Overview of parallel architectures and communication; parallel programming paradigms; performance models of parallel computation; parallel algorithms and applications; systems and compilers for parallel languages.

### Applied Mathematics:

CSE students whose home department is not Mathematics must take one of the following sequences:
