i looked at uBLAS and the design seemed obsolete to me so i thought there could be a better approach then blindly following blas design
What is the issue with uBLAS?
in my opinion a piece of software must be targeted to target users (excuse for a pun) i see a generic scientist as target user who already knows about matrix calculus and may not know about blas for such person writing u = A*v + w is much more natural than that of blas terms i think that user must focus on the design and the intent rather than how to express the thing in blas terms
Please note we're not talking about BLAS (C interface), but uBLAS which is already a Boost vector/matrix library here: http://www.boost.org/doc/libs/1_39_0/libs/numeric/ublas/doc/index.htm You also need to be very careful with allowing "simple" expressions like u = A*v + w As traditionally these have awful performance due to the temporaries involved. There is also an ongoing Boost-sister-project to devise a "next generation" matrix library for C++, but I've lost the link for the moment :-( Cheers, John.
