Java applet. Use it at your own risk.
You will be using Mathematica
to solve some of the problems. PANIC cluster has
a license for more than ten processes, and socrates has an unlimited
license. A student license can be purchased from The Scholar's Workstation at $134,
a hefty discount for PCs and Macs from the regular academic price of $895.
To use Mathematica remotely on socrates or PANIC, you need an
X-server software on your computer. On Windows, go to http://software.berkeley.edu/
and install Exceed. Click here for more
detailed instructions by Adam Bryant, a 221A student back in Fall
2004. If you know of a better/updated method, let me know.
On Macs, you can install X11 from system disks (see instructions). Then
login to socrates with an option
% ssh -X firstname.lastname@example.org
to enable X11 forwarding over the secure channel.
Linux and other Unix machines, X11 must be a part of the standard
installation. Login to socrates the same way as on Macs.
Mathematica version 3.0 on socrates needs special fonts. Before you
% xset fp+ tcp/socrates.berkeley.edu:7100
in your X-windows software (e.g., Exceed or X11)
to use the font server on socrates. Despite the warning on fonts
(just click OK), it seems to work fine. Mathematica version 5.0 on
PANIC does not require a particular setup on your end.
After logging in with X11 forwarding, type
% mathematica &
to start a Mathematica session.
To print from Mathematica, probably the easiest is to install
on your PC,
sftp your notebook file
to your PC, open it with MathReader, and print it from there.
Another way is to use Mathematica on socrates, go to File menu
and choose Print. A dialog box appears:
For Print Destination,
choose File and specify the filename. Make sure that "Include
Mathematica fonts in document" is chosen. Click OK and the notebook
is saved as a postscript file. A postscript file can be previewed
% gv xxx.ps To print it from your PC, convert
it to a PDF file with
% ps2pdf xxx.ps and then
sftp the file
to your hard drive, open it with Acrobat Reader, and then print. To
print only the graphics (or just one cell in general), choose the
cell by clicking the blue square bracket on the right, go to File
menu → Save Selection As → EPS → give a filename
xxx.ps, and the rest is the same.
Daniel Larson, my former student and currently a lecturer at
Harvard, wrote a sample notebook
to get you started with Mathematica. You are not required to
use Mathematica in this course, but I will post solution sets in
Mathematica notebooks and design problems assuming you will be using
Mathematica. I suspect Maple would do probably fine. I am less
sure with Matlab, especially in the area of algebra. Share your
stories with us!
- I do not plan to distribute copies of syllabus, homework
problems, solutions, lecture notes, etc, to save money and trees.
- You can access most of the journal articles through UC Berkeley
electronic subscription from berkeley.edu domain, or from any other
domains through the proxy server of the UC Berkeley Library. See instructions to use the
proxy server. You need a valid CalNet ID.
- You are encouraged to work with your friends on homework. But
you have to work on your exam on your own.
- I don't have a strong opinion between in-class and take-home
exams. I let you vote. Unlike homework, you have to work by
yourself on exams. Each exam counts as two homework in the final
