This is usually not a problem for the kinds of analysis I'm talking
about.  The data sets are infinitely large, but the whole point of the
analysis is to summarize them statistically and that reduces to a
matrix of known dimensions, independent of the number of observations.

That depends on whether Matlab already has the optimized libraries.
This is unlikely for state-of-the-art crisis-causing derivative
securities and/or theoretical advances.
