I can't speak for Joe's class, but when I've asked Matlab users here
about using Octave instead, they're generally not interested. Partly
this is a somewhat irrational "it doesn't have Matlab on the cover"
thing, but largely it's the Matlab toolboxes they want access to.
A recurrent theme we find with anyone doing stuff with any similar
package, be it Matlab, Stata, R or whatever, is that they always hit
massive difficulties when they try to scale up their analysis to
larger problem sizes. If they come to me early in their project, I
will point this out in advance, and suggest that while such languages
are great for prototyping, they don't scale well. Usually, of course,
the warning is ignored (they didn't pay for this advice, so no need to
take it, right?) and six months down the line their stuff doesn't work
any more when they try to run it on large production datasets, and I
have to avoid the "I told you so" speech... :-)
People have mentioned Hadoop here, and it might work for some types of
work being done (I'm interested in the data-locality feature of its
filesystem that was mentioned earlier in the thread) but no-one's
using it at this site yet as far as I know.
