Hi David,

Good job!
IMHO uBLAS lacks many functionalities to make it a general-purpose
linear algebra lib, and I'm very happy to see them now in TODO :)

Two simple questions:

"#  vector/matrix ew_op scalar: elements wise arithmetics operations"
What does it mean? Maybe, aggregator functions like sum(.), which sum
of elements of a vector/matrix expression?

# SVD, Cholesky, LU, QR, Shur
Do you think this should be written from scratch or maybe using
existent solvers like the one provided by LAPACK (possibly using the
boost::numeric::bindings lib)?

Thank you very much

Cheers,

-- Marco
