MATLAB newsgroup? Ha. There are a few very knowledgeable posters (and
a pretty good showing from the mathworks.com domain) but the S/N is so
poor it is very difficult to learn anything from it. But the IDL
newsgroup... A valuable resource. Indispensable. And not a single
reference to it on the RSI website. <sigh>

And I should clarify that MATLAB uses a "lazy" copy where it will not
make a copy until you change the data. But this really doesn't help me
right now. At least MATLAB has a 64bit linux version and a beta 64bit
winXP version available. When in doubt, throw more memory at the problem.

As an aside, I think MATLAB definitely has some features over IDL (GUI
builder and Java integration), and IDL over MATLAB (keywords and
pointers and the VM). Ooooh the VM. You all should thank RSI for that.
Mathworks charges a lot of money for the exact same thing.
