Of course, U*D*V (transpose omitted for clarity) is the classic
problem for an interpreted language: the creation of temporaries.
weave allows you, via blitz, to do chained matrix/matrix operations
without multiple passes through the loop and w/o temporaries by
run-time compilation and linking of extension code. Perhap's the OP's
reference to JIT is referring to a just in time compilation mechanism
in matlab, similar to weave's. They've already discovered LAPACK and
FFTW; it wouldn't be surprising if they solved blitzm (blitz in
matlab), antialiasing, alpha transparency and multiple colormaps per
figure in upcoming releases.
