Additional resources by topic are listed below, to be updated regularly.

Student-editable Q&A wiki, where you can post q's and resources.

EXAM PREP- while i give no guarantee of full coverage, I have made efforts to make my slides/worksheets reflect what I would expect on an exam.

• Go through all my slides, and make sure you get the concepts. Whenever I do a numerical or practical example, do it yourself! change a number, or get your own image, and do it.
• do my worksheets!
• Later today, I will post some things that have shown up on previous exams. Unfortunately I cannot post sample questions.
• I will still be available via email over the weekend.

more fourier and assignment 2

So, I have decided to use the lab time over the next weeks to introduce each assignment, one by one, starting tomorrow. This will hopefully help those interested to get started and will allow you to ask initial questions. The assignment will be discussed at the end of the lab so those not interested can leave early.

Assignment Submission Instructions

DUE DATES: Last days to submit your assignments:

Please email your assignments as follows:

• send to cpsc535@gmail.com
• subject line: [user id] Assignment #. For example, [308442] Assignment 1
• attach the assignment to the email. if it is a single file, attach that. Feel free to use zip/tgz/rar for larger submissions
  • please attach all relevant files. This includes source, generated images, write ups (see below), etc.
• if i have trouble executing your code, I will require a live demo!
• late submissions will not be accepted

Also, submit a hard copy which includes

• code print outs
• plots
• your write ups

For your write ups:

• word (.doc/.docx), .pdf, OpenOffice, postscript, are acceptable.
• put your name and ID in the document
• explain methods and approach, pitfalls, difficulties
• explain algorithms not taught in class
• give result images/diagrams/numerical data, and an analytical discussion of what your results mean.

Basically, show me that you understand the methods you use, why you use them, and why the results you gain are significant and useful.
