Jared,
4GB of RAM should be enough. The problem is whether Matlab or your
operating system can actually use them. In my experience the only way
to make full use of your RAM is to run Matlab under Linux. Windows XP,
Vista, or mac OS X will fail.
Hope this help,
Best,
GAR

"The point of public relations slogans like "Support our troops" is
that they don't mean anything. [...] That's the whole point of
propaganda. [...] Its crucial value is that it diverts your attention
from a question that does mean something: Do you support our policy?
That's the one you're not allowed to talk about. [...] The people in
the public relations industry aren't there for the fun of it. [...]
They're trying to instill the right values. In fact, they have a
concept of what democracy ought to be: It ought to be a system in
which the specialized class is trained to work in the service of the
masters, the people who own the society. The rest of the population
ought to be deprived of any form of organization, because organization
just causes trouble. They ought to be sitting alone in front of the TV
and having drilled into their head the message, which says, the only
value in life is to have more commodities or live like that rich
middle class family you're watching and to have nice values like
harmony and Americanism. That's all there is in life."
