Hi,

for uBlas, the main project is indeed to improve the current framework to
allow the integration of SSE, GPU, multi-core etc... and the make writing
new algorithms easy.
I want also a unified representation of vector and matrices. So far, we are
like in R, a vector is a array in the C-style, while a matrix is really a
class representing thanks to a 2-dimensional array, the notion of a
mathematical matrix. In other libraries they only have one base
representation for all of this.

We have a lot of duplicate code and I don't see the difference between a
1-row or 1-column matrix and a vector (at least not in my math textbook).

The advantage to factorize code is obviously to be able to apply in a uniform
way and with less work all these techniques like SSE, etc...

Cheers,
David
