[Boost-users] how to get started with the boost uBlas thing?

Hi all, I recently installed the Boost library and I am interested in using the Boost.UBlas library along with the Boost.UBlas bindings. Since, I have never even used Linear Algebra packages like BLAS,LAPACK,ATLAS etc., I am finding it very difficult to get started with Boost.UBlas or the bindings library. I am especially finding it very hard to find which method is appropriate to call for a particular task due to the huge set of functions provided by BLAS. It would be nice if I could get pointers or suggestions to get started with these linear algebra packages. Some good tutorial on using them or atleast good documentation that help me out in finding which method is appropriate to call. Thanks. Ajay G.
