Math 128b - Numerical Analysis - Spring 2014

Announcements: I will post what material was covered in class here after each lecture.

Homework: is posted every Tuesday on this website and is due the following Tuesday in class (before we start the lecture).

How to hand in code: if the HW requires you to write and test code, please hand in the following as hard copies: (1) the results your code produces when you apply it to the problem asked for in the HW, e.g. a print out of Matlab's command window where you use your code; (2) print outs of the code of all functions that you call (except the Matlab routines).

Lecture: Tuesday and Thursday 3:30-5:00 pm in 2 Evans.

Discussion: Thursday 11:00-12:00 in 285 Cory.

Instructor: M. Morzfeld, office hours: Mondays 1:00-2:30 pm and Fridays 1:00-2:00 pm in 971 Evans. Email: mmo [at] math [dot] lbl [dot] gov

GSI: Christopher Wong, office hours: Mondays 4:00-5:00 pm and Thursdays 5:00-6:00 pm in 1039 Evans. Email: cawong [at] math [dot] berkeley [dot] edu

Prerequisites: Math 110 and 128a or equivalent knowledge of numerical analysis and linear algebra.

Textbook: T. Sauer, Numerical Analysis, 2nd edition, Addison-Wiley, 2012.

Software and computer lab access: We will use Matlab for coding and testing algorithms. Matlab is available in the "Calculus Microcomputer Facility" (CMF) in B3A Evans. Please check their website for availability. We have reserved access to B3A Evans on the following days:

Syllabus: Math 128b is a second course in numerical analysis. The course will introduce standard numerical methods for

We will find out when, how and why the various algorithms can be expected to work. Analytically, we will focus on stability and accuracy properties. Computationally, we will write our own codes and also study and apply Matlab's routines. The lectures will follow, amplify and explain the textbook, with additional handouts when other material is required. Student participation will be encouraged during lectures.


No books, calculators, computers or other aids will be permitted. You can bring one sheet of handwritten notes (both sides, if you want). No make-up exams will be given. If you miss the midterm, your score on the final will count in its place. If your final exam score is higher than the midterm score, the midterm score will be replaced by the final exam score.

Grading: 40% weekly homework and quizzes, 30% midterm, 30% final. The lowest two homework grades will be dropped from the computation. Four quizzes will be given during discussion sections. Each quiz counts as much as one homework assignment and the two lower scores will be dropped. Thus the final course grade will be computed from the formula 0.4 * (top n - 2 of n homework grades + top 2 quiz scores) + 0.3 * max(midterm grade, final exam grade) + 0.3 * final exam grade where each parenthesis is a number between 0 and 100.
