Math 128A - Numerical Analysis

Prof. Per-Olof Persson, Fall 2026
Department of Mathematics, UC Berkeley

Course details

Readings and other materials

MATLAB requirements

The MATLAB programming language will be used for homework and programming assignments. There are several ways to use it:

If you have little or no prior programming experience, we highly recommend reviewing a previous offering of Math 98 (MATLAB for Math 128A).

Grading and policies

AI, Collaboration, and Resource Use Policy

In this course, your goal is to master the material, not just produce correct answers. For the homework and the programming assignments, you are encouraged to learn from any available resource, including collaborating with classmates, consulting online materials (e.g., Stack Overflow), and using AI assistants (e.g., Gemini, ChatGPT). These are powerful tools for brainstorming, debugging, and understanding complex concepts. However, the fundamental rule is that the work you submit must be your own. You are responsible for understanding and being able to explain every part of your solutions and every line of your code from scratch.

Think of it this way: discussing mathematics and algorithms with a friend is valuable, and asking an AI to explain an error can be useful. However, simply copying a solution from any source without understanding it is academic dishonesty. You will be tested on these concepts in quizzes and exams, where these resources and collaborators will not be available. Homework is your opportunity to practice and genuinely learn the material, so make sure you are the one doing the learning.
