Please help us to make the course better for those that follow you in future offerings. Take a few seconds to give us some feedback through the course survey system at

The remainder of your grades will be posted by Thursday at noon. You have until Friday at midnight to discuss a grade with your TA. After that point your TA will lose access to your grades and your grades will be permanent. Please check over your grades and make sure you are comfortable with what you see.

Since 'tis the season for final exams, we have some good news and some bad news for you:

• First the bad news: You may only take the CS1371 final exam during your regularly scheduled exam time. If you have legitimate conflict, as in you have three exams on the particular day you take CS1371's exam, reschedule with a lecturer BEFORE your regularly scheduled exam time. If you oversleep or something on your exam day, we can't help you.
• Now the good news: If your final exam grade is higher than the average of your three tests, we'll replace each test grade with your final exam grade.

11/14/03 (18:53:55) Homework 11 up and ready

Homework 11 is now available on the course website. It will be due November 30th at noon. However, there is a significant amount of extra credit that can be obtained in this assignment. Be sure to download the assignment as soon as possible and read over it.

Lab 4 is now available on the course website. It's a cake walk. It's even easier than Lab 1. It is due November 21st at noon. P.S. Happy Birthday to our magnificent and fearless Head TA.

By now you should all be in groups for the last two homeworks or have received an assignment from your TA. If you do not have a group, email your TA and ask for one.

Due to the WebCT failure on friday, we are extending hw9 yet again. It will be due Wednesday at noon. This is primarily to allow you to verify your submission is unaffected by the failure. Please be sure and make sure this is the case and resubmit if necessary.

Homework 10 is now available on the course website. It is due Wednesday, November 12 at noon. ONE of your group members needs to submit the finished project to WebCT under hw10. The remaining group members must submit a plain text file specifying the group member's name and gtnumber who submitted the completed assignment.

Because there are still a considerable number of you that can't seem to get Java working because of Matlab's issues with Java, we are extending the homework to be due at noon on November 3rd.

There have been some questions regarding the instantiation of the Rectangle class in Homework 9. Because "Rectangle" is part of Matlab outside of Java, saying "r = Rectangle" may cause some problems. To solve this problem, you can either:

• rename your Rectangle class to "MRectangle"
• use the Matlab function "java_object" to instantiate Rectangle. This function is discussed in your book.

The two remaining homework assignments after homework 9 will be a little bit different. They will be two-week long group projects. With this in mind, it is extremely important that you set up your groups by 11:59:59 PM on Friday. Groups will be of either 3 or 2 people but we enourage you to form groups of 3 as the projects will be more extensive than the homeworks.

Each student needs to email their TA with a list of ALL the members of their group by that time on Friday. If you do not, your TA will assign you to a group and you will not be permitted to change groups.

You may only select group members that are assigned to your recitation. This means your partners must be either in your oscar section or the other oscar section that shares your recitation.

We strongly encourage you to attend recitation this thursday. We will be allowing 10 minutes or so for you to mingle with your fellow students in recitation and form groups.

Those students in section C5 that currently are being taught in room 209 will need to report to room 107, where C6 and the rest of C5 is, for the first few minutes of recitation in order to form teams with the rest of your recitation. You are not to form teams with section C1 and C2.

The html lab is now available on the course website. This is a two week lab due on November 7th at noon. After the due date, you may not alter your html files until the lab has been graded by your TA. We will be checking to make sure you have not altered them after the due date. For a demonstration of a completed lab, visit the following website:

Homework 9 is now available on the course website. Please turn in all files to WebCT by October 31, 2003 at noon.

WebCT is now fully operational. We apologize for the trouble over the weekend and hope nobody was inconvenienced too much. The registrar, during some paperwork, didn't quite realize the side effects of their actions. Homework 8 and Lab 2 can now be submitted.

Lab 2 is now available on the course website. It will be due to WebCT by 12 noon on October 24th.

Homework 8 is now available on the course website. It will be due to WebCT by 12 noon on October 24th.

Practice Test 2 is now available on the course website.

Homework 7 is now available on WebCT and the course webpage. Please turn in all files by 12 noon on October 10th to WebCT.

We thought this might help folks understand the game of life a little more. It has graphical representations of different states and offers some in depth information on the game:

Because you are now learning how to use newsgroups in Lab 1 (see announcment below), we are making a transition in the way TAs provide you online help with course materials. Two newsgroups are now available on news.gatech.edu for your use:

• git.cc.class.cs1371.rec A forum for discussion and questions regarding homeworks
  
• git.cc.class.cs1371.lab A forum for discussion and questions regarding labs
  

[assignment #][problem #] topic

The TAs will be supporting both newsgroups and WebCT discussions during this transition time. However, after Lab 1 is due, the discussion groups will be taken offline. Newsgroups are advantageous for several reasons:

1. As it stands now, each of the three lecture sections has a distinct and separate discussion group. Students do not see and thus benefit from questions asked by a student in another lecture section. The newsgroups will be shared across all lecture sections.
2. Due to a quirk in WebCT, some TAs posting messages to the discussion groups appear to be the lecturer for that section. This will not be the case with newsgroups.
3. Because discussion groups are web based, each click on a link causes a refresh of the page which makes for slower navigation.

Lab 1 is now available on the course website. All requirements must be completed by October 10th, at 12 noon with the usual 6 hour grace period.

In Problem 2.1, equation 7 the exponent should be negative. Thus the equation should be:

(cosx)(cosy)e^(-sqrt(x^2 + y^2) / 8)

Homework 6 is now available on WebCT. It is due to WebCT by October 3rd at 12 noon with the usual six hour grace period.

As many of you may know, due to a problem in OIT, WebCT was down between Monday evening and late Tuesday afternoon. Unfortunately there was some data loss. OIT has restored all of this data but if you submitted hw5 since it was released, please make sure your hw5 is as it was when you submitted it. If it is not, you may resubmit the assignment. As a result of this inconvenience, we are extending hw5 to be due on monday at 12 noon with the normal 6 hour grace period for all sections. Please contact your TA if there are any questions.

There has been some confusion over the provided show_img function in homework 5. This function was only intended to be used with the image of Lenna for you to look at .mat files. We realize this was not clear in the homework file. You may use image(*image array*) or imwrite to view the images your functions create.

You are not permitted to use any Matlab image manipulation functions that directly solve the problems in the homework. For example you may not use any kind of rotation function provided by Matlab in the rotate problem. You need to implement the logic yourself. The instruction file has been updated to reflect this.

Homework 5 is now available. The instructions are on the course website and the necessary files are available on WebCT. You will turn in the assignment to WebCT.

There has been some confusion over the email announcing a room change for David Smith's lecture this Thursday. To clarify, David Smith's lecture at 9:30 has been moved to room 100 in the management building at Technology Square. The change is only for Thursday, September 18th. The lecture will resume at it's normal location next Tuesday. This change does not impact the test scheduled for Thursday night. It will be at the scheduled time in your recitation room in the IC.

Please be aware of the following for Thursday's Test:

• You must bring your BuzzCard (or other government-issued PhotoID) to all exams
  
  
• A reminder of our academic misconduct policies: You may receive a zero on this exam, an F grade in the course, and/or other disciplinary action if you engage in the following:
  • Communication with anyone other than a proctor (TA) for ANY reason in ANY language in ANY manner.
  • Sharing of ANYTHING (e.g. pencils, paper, erasers).
  • Writing on paper that is not given to you by a proctor.
  • Cell phones, beepers, hand-held computers, calculators, etc. in your possession during the exam.
  • Failure to follow directions given by the proctor.
  • Failure to stop writing when the allowed time is up (as reported by the proctor).
  • Using books or other reference material.
  • Disruption of the exam setting.
  
  
• WebCT calendars have been recently updated to reflect the correct dates for Exams #1, #2 and #3, which will all be held during Recitation.
• The test is 90 minutes long. There will be a short review session in the first 15 minutes of recitation.

A practice test is now available on WebCT under assignments. It will not be graded and is strictly optional. You do not need to submit anything back to WebCT.

Updated the class code in the lecture section to reflect today's creations.  DMS

9/9/03 (20:44:34): Hw4 - Problem 1.2

Please be sure to average non-negative values in this problem. This includes zero. The sample matlab code averaged positive values but this has been changed in the newly posted file.

There was an inconsistancy between the table of ternary values and the description in the paragraph below the table. The table contains the correct values and the updated file on WebCT has been changed to reflect this

There is no flip.m file required in your submission of hw4. This was a file left over from one of the problems we considered but later rejected for this homework. An update of the pdf file on WebCT reflects this.

An additional file has been added to the hw4 download. If you've downloaded hw4 already, please retrieve hw4.pdf in addition to the second file.

Homework 4 is posted on WebCT. It is due at noon on Friday, September 12 with a six hour grace period.

Due to some confusion about the six hour grace period in the syllabus, the deadline for the submission of homework 3 has been extended to 11:55 PM on Sunday, 9/7/03.

All recitation rooms are being moved to the Instruction Center. Skiles is too cramped for everybody. In addition, your TA will have the opportunity to use the computers in the IC to demonstrate concepts. The room assignments are available in your lecture but they are also posted below:

Homework #3 is now posted on WebCT. It is due at 12 noon on September 5th.

Update: As of Sunday evening 8/24/03, Homework #1 is now posted on WebCT, and is due by Friday August 29^th, at noon. You are to submit your solution file for Homework #1 via the WebCT Assignments page for your class section, using the [Upload File] feature.

Also, Homework #2 is now posted on WebCT, and your solutions file for Homework #2 is due by Friday August 29^th, noon (the same as Homework #1).
