S. E. Chapra: Applied Numerical Methods With MATLAB for Scientists and Engineers.
(3rd edn.) ISBN-10: 0073401102; ISBN-13: 978-0073401102, McGraw-Hill (2011).

UBC Bookstore has new and used books for purchase or rental. Besides, an online version of the textbook is also available.

MATLAB will be required for our course. The software package is available on all CHBE machines in the computer labs (CHBE 314). Besides, you can install the 2X client on your own laptop computer according to the instructions posted on our CHBE 230 home page on connect.
Exams and grading formula

Final Grade = final exam (50%) + midterm (30%) + tutorial & quizzes (10%) + homework (10%)
  • Midterm: tentatively scheduled for Feb 11, 3:30-4:45 pm in CHEM B250.
  • Final: date and time to be announced, to be written in Computer Rooms.
  • Missing a quiz or the midterm results in a score of 0, except with prior consent of the instructor or with a doctor's note. In these latter cases, you will receive no score from the missed quiz or midterm, and its weight will be shifted to the other quizzes or the final exam. If you have a legitimate reason for missing the midterm, for example, your final exam will count for 80% of the grade.
  • Weekly assignments will be posted on the course website on Connect. Due dates will be announced later. Late homework will receive no point.
