Mathemagix

Hi all,

In my current work with Andre Galligo, I need some analytic continuation 
process for high degree polynomials (something like 100), and I am 
looking to make this using mathemagix (because it includes fast 
algorithms which are needed with such degrees, and also because there is 
some time that I want to use this).

In some talks given by Joris, he showed some example where mathemagix 
was making some analytic continuation process. On the mathemagix 
website, I saw that this was include in the analyziz package, but nor 
more information are given here. As I am not used to this language for 
the moment, I would like to know which functions could be usefull for my 
purpose, what is really done in mathemagix, and what is not.

More details about what we need : we would like to make analytic 
continuation along some paths (3 in practice) without of course 
computing all the singular / critical points (which are too many with 
such degree). Thus, the two points I see are the analytic continuation 
process on one hand, and the detection of close singularities during the 
process on the other hand.

These subjects have been studied in Joris paper's, where he says that he 
started the implementation in mathemagix, but is this work ended and 
available ? And if yes, what do we have to use ?

Best regards,

Adrien
