All EE123 students can have "named" accounts on our Instructional
computers, which include UNIX, Windows and MacOSX. Matlab runs on
them all. Students can use the computer labs in 199, 105 and 119
Cory. Most students already have computer accounts that work in
those labs.
How to get a "named" account:
http://inst.eecs.berkeley.edu/connecting.html#accounts
(go to 199 Cory, login as "newacct" with password "newacct").
We have MATLAB on all instructional Windows and UNIX systems,
including the remote-access servers:
http://inst.eecs.berkeley.edu/~Einst/iesglabs.html.
We have the Signal Processing and other toolkits, listed on: http://inst.eecs.berkeley.edu/cgi-bin/pub.cgi?file=matlab.help.
MATLAB Signal Processing Toolbox and Signal Processing Blockset
are available on the Windows computers in 199 Cory and 105 Cory.

Problem sets handed in late will not be accepted unless consent is
obtained from the teaching staff prior to the due date.

A pdf version of the lecture notes will be on line on the class
web page by the end of the day on which the lecture is given.
