ACMS 40390 - Numerical Analysis

You must be registered for this course. If you are planning to register but have not done so see me.
Until either the registrar or I know about you, you will be unable to do any work specific to this course.

You should have an active ND email account.

You must have an AFS password.

Both your email and your AFS account contain sensitive information with regard to this course.
It is your responsibility to protect your password for your NetID (AFS password).
If at anytime during the semester you suspect that your password is known to others, change it immediately.

You need access to a computer to do your homework. It can be your own machine or any of the lab machines. Indeed it can be any machine from which you can access AFS space.
To access your AFS space you need some version of ssh on your machine.
- LINUX or any other flavor of UNIX has ssh from the command line any terminal window.
- Mac OS X has ssh from any terminal window: type ssh darrow.cc.nd.edu -l yourafs_id in the terminal window.
- Mac OS 9 users will need to install MacSSH (or any other ssh client you prefer).
- Windows users will need to install putty (or any other ssh client you prefer).
You may need to move files from the machine on which you are working to your AFS space.
- Mac OS X has sftp from any terminal window. For a better interface you can install Fetch 5.0.5 (or any other sftp client you prefer).
- Windows users can install openafs which mounts your AFS space as drive H:. Bitvise Tunnelier or Winscp can aslo be used to run sftp. And of course, if you have another favorite sftp client use it.
- In any OS you can use webfile.
- You can use the vi editor. Login to darrow.cc.nd.edu using ssh, cd to the relevant homework directory and start up vi by typing vi file.cpp (where file.cpp is the name of the file you want). Then hit enter/return; then type i (for insert); then copy the contents of the file on your computer and paste them into the terminal window. Finally type, ESC, then :wq and your file is uploaded.

Some acquaintance with UNIX is needed. At a minimum you need to know how to
- OIT's document, U1010 UNIX for beginners, is a good basic introduction. Much of the specific information about the actual setup at Notre Dame is out of date, but the sections on basic UNIX are still good.

There is a text editor vi in AFS space that you can use to create or fix files. It is a modal editor meaning that different things happen when you type, depending on which mode you are in. There are two modes, Command mode and Typing mode.
- Use vi filename to open a file. It opens in Command mode.
- Use vi (without a filename to get a copy of the Vim manual - Vim is vi).
- Use arrows to go left and right, up and down in either mode.
- Use o in Command mode to go to Typing mode and open a new line.
- Use "ESC" to go back to Command mode from Typing mode.
- Use :w to save your file from the Command mode (remain in Command mode).
- Use :q from the Command mode to quit (:wq saves and then quits with one command).
- Use x in the Command mode to delete (remain in Command mode).
- Use i in the Command mode to go into Typing mode.
- Similar to x, there is also dd for deleting an entire line in Command mode (remain in Command mode); 5 dd deletes the next 5 lines.
- Similar to i, there a for append (change to Typing mode).
- If the cursor is over a brace, bracket or parenthesis in Command mode, the % key will jump it to the matching brace, bracket or parenthesis (the utility of this will become apparent as the course develops).
