[boost] Eigen vectors?

Hi all, I am very new to boost, and I thought I'd do some simple linear algebra examples to get started. I got some simple vector/matrix multiplications going with .../boost/numeric/ublas/vector.hpp and matrix.hpp. However, I didn't see any function in the documentation do find eigen values or to do factorizations or anything like that. Are those kinds of functions not included, or am I crazy and just missed them in docs? -- Thanks, David
