Dear Octave-Experts,

I'm mainly developing new mathematical non-commutative algebraic

theory. Right now I'm working on a complete new family of semi-

definite solvers for optimization (the preprint might be on arXiv

by the end of the year). The free field is a rather abstract ob-

ject. I do have an experimental implementation in FriCAS but con-

sider to write it in C/C++ building on GMP with an interface to

Octave (which I use for numerics).

There are two sections in

http://wiki.octave.org/Projects I'm

very interested, namely »High Precision Arithmetic Computation«

and »Sparse Matrices« (mainly for semidefinite programming).

Could you please tell me briefly what the current status is and

give me some contact person for exchanging some ideas offline?

I'm very deep in programming (in ancient times I even used

assembler ;-) up to abstract mathematical modelling. But I do

not have experience with huge software projects. On the other

hand I'm very interested in bringing new mathematical theory

and algorithms to a broad audience.

I followed the discussion on matrix functions in detail and

know the difficulty because I once programmed some myself using

the book of Higham (2008). How is the status (briefly) here?

Not that I can contribute substantial development right now

due to the lack of ressources but I do have ideas for develop-

ment on a meta level, i.e. to generate high level mathematical

code ...

Thanks!

P.S. I would rather like to stay in the background.
