A graduate course in Mathematics at the Department of Mathematics, National Tsing Hua University.
Instructor: Professor Wei-Cheng Wang,
Class meeting: ºî¤T 734. Meeting schedule: W567.
First meeting: Wednesday 2/18, 1:10 PM.
Grading: 3-4 sets of homework assignments, mostly programming.
Textbook and References: Typed lecture notes will be distributed in class. You can refer to any standard numerical analysis textbook for materials not covered in this course. For example: Cheney, E. W. and Kincaid, D: Numerical Mathematics and Computing. or Shampine, Allen and Pruess: Fundamentals of Numerical Computing.
Course description: This course is a continuation of the undergraduate course `Numerical analysis' with emphasis on practical applications including numerical methods for differential equations, impage processing and mathematical finance. Students are required to do independent homework assignments on programming using modern languages (any one of matlab, c, c++, fortran ...). Some knowledges on numerical programming. and a preliminary undergraduate course of numerical analysis (or equivalent) is preferred, but not required. Undergraduate students are welcome. If necessary, we will have a short tutorial on matlab so that everyone can proceed. We will also arrange computer lab hours to help you resolve programming problems.

Netlib is an excellent net resource. It contains tons of reliable numerical software that can be downloaded and links to most technical information on numerical analysis and scientific computing on the internet.

Matlab is an excellent environment for experimentation in scientific computing. It is not the most efficient environment for large-scale simulations, although with some effort, Matlab can be used in conjunction with C and Fortran routines. Matlab is a product of The Mathworks. For a tutorial, see A Free Matlab Online Tutorial or Another Tutorial or Matlab PrimerA short tutorial for C programming language.
