Re: [eigen] Student contribution proposal

[Gael Guennebaud <gael.guennebaud@xxxxxxxxx>]

Hi Simon,

I always welcome contributions :) especially if they are consolidating
existing modules.

I'm afraid the Todo-list, it is pretty out-of-date. Regarding the SVD
module, there is still a need for a faster SVD than the current
two-sided Jacobi algorithm. There are many discussions on this topic
in this mailing-list. I could gather them for you. In very short, the
divide-and-conquer algorithm seems to be the best approach.

The QR module is pretty complete with three versions of Householder QR
(no, column, and full pivoting). The column-pivoting version still
need to be accelerated by working on blocks of vertical panels.

It would also be nice to have methods to compute the kernel for all
rank-revealing factorizations (SVD, ColPivotingQR, FullPivotingQR) as
already done in FullPivLU.

If you had other ideas in mind, feel free to propose them.

cheers,
Gael.
