[Numeric] Numeric Digest, Vol 10, Issue 1

(I've hit "send" by mistake)

as I was saying, I'm working on some libraries that might make it into
next year's NPFL or FHPC (hoping that ICFP will take place in Europe
or surroundings).

I understand your concerns with HMatrix; it's a widespread and useful
library and it deserves an appropriate home.
Perhaps it's also time to think about a dedicated documentation site,
similar to that of accelerate (http://www.acceleratehs.org/) ?

Kind regards,

Marco Zocca
