Hi,

after answering Thomas questions, I realized that we still have a few good projects which are not very well known in the ublas community. It would be good to have a look at them again together and push the code into the main library.

On top of my mind, I remember the following:

- optimized multiplications with impressive speed-up: https://github.com/BoostGSoC17/uBLAS. It was a great great work!

- an EigenSolver: https://github.com/BoostGSoC15/ublas. This one too was a top-notch work. I mean like really really good. Worth having a look too.

- optimization of the expression template tree: https://github.com/BoostGSoC14/boost.ublas. Impressive work on symbolic manipulation of ublas expression at compile time. I think there is a lot of potential in this one too. And with C++17 and 20, I'm sure we can do a lot more.

Best regards,

David
