There are over over 2500 messages. I don't have the luxury to "browse"
through these messages for no specific purpose. If you want to point me to
something specific I would be happy to read it.
I did however do my homework which I think earns me the right to make a
dismissive statement. I read the documentation (what was available, it is
still broken), I read the effective ublas wiki entry, I read gunter's guide,
I asked questions first, and I did a detailed comparison of performance of
ublas with two separate matrix implementations, along with std::valarray.
My point is simple: any matrix/vector library (especially as part of boost)
should at the very least be able to perform better than a naive
implementation, or a standard library implementation (std::valarray), in its
most intutitive form (for instance v += u) without requiring the user to
read reams of documentation, ask questions on newsgroups and mailing lists
or have to use extra functions.
